## Area of Regular Shapes Worksheets

**Example 1.
**Find the area of the below figure

1.

2.

3.

**Solution:**

1. Area of the rectangle=length × breadth

The length of the rectangle=12

The breadth of the rectangle=10

Area of the given rectangle=12 × 10=120 sq cm

2. Area of the square=side × side

Given side of the square=7 m

=7 × 7=49 sq m

3. Area of the rectangle=length × breadth

The length of the given rectangle=14 cm

The breadth of the given rectangle=15 cm

=14 × 15=210 sq cm

**Example 2.**

Find the area of the figures

1.2. 3.

**Solution:**

1. Length of the rectangle=8 cm

The breadth of the rectangle=9 cm**
**Area of the rectangle=length × breadth

=8 cm × 9 cm=72 sq cm

2.Length of the rectangle=16 cm

The breadth of the rectangle=11 cm

Area of the rectangle=16 cm × 11 cm=176 sq cm

Hence, the area of the given rectangle=176 sq cm

3. Length of the rectangle=16 cm

The breadth of the rectangle=21 cm

Area of the rectangle=16 cm × 21 cm=336 sq cm

Hence, the area of the given rectangle=336 sq cm

**Example 3.**

Find the area of the following figures

1.2. 3.

**Solution:**

1. Length of the given rectangle=15 m

The breadth of the given rectangle=5 m**
**Area of the given rectangle=length × breadth

=5 m × 15 m=75 sq m

Therefore, the Area of the rectangle=75 sq cm

2. Length of the given rectangle=16 cm

The breadth of the given rectangle=5 cm

**Area of the given rectangle=length × breadth**

=16 m × 5 m=80 sq m

Therefore, the Area of the rectangle=80 sq m

3. Length of the given rectangle=23 m

The breadth of the given rectangle=7 m

**Area of the given rectangle=length × breadth**

=23 m × 7 m=161 sq m

Therefore, the Area of the rectangle=161 sq m.

**Example 4.**

Find the area of an equilateral triangle whose perimeter is 18 cm?

**Solution:**

Given perimeter = 18 cm

We know that the perimeter of an equilateral triangle = 3a

Therefore, 3a=18

a=18/3=6 cm

Hence, the length of the side of an equilateral triangle is 6 cm.

Area= \(\sqrt{ 3 }\)a^{2}/4 sq cm

=\(\sqrt{ 3 }\)6^{2}/4 sq cm

=\(\sqrt{ 3 }\)36/4 sqcm

=9\(\sqrt{ 3 }\)sq cm

Therefore, the area of an equilateral triangle is 9\(\sqrt{ 3 }\) sq cm.

**Example 5.
**Find the area of an equilateral triangle whose side is 4 cm?

**Solution:**

Area of an equilateral triangle=\(\sqrt{ 3 }\)a^{2}/4

=\(\sqrt{ 3 }\) 4^{2}/4 cm

=\(\sqrt{ 3 }\) 16/4 cm

=4\(\sqrt{ 3 }\) sq cm

Hence, the area of an equilateral triangle is 4\(\sqrt{ 3 }\) sq cm.

**Example 6.
**What is the area of the circle if the radius is 14 cm?

**Solution:**

Given radius=14 cm

Area of the circle= π × r^{2}

=22/7 × 14 × 14

=22 × 28

=616

Hence, the area of the circle is 616 sq cm.

**Example 7.
**If the diameter of the circle is 14 cm. Find the area of the circle?

**Solution:**

Given diameter=14 cm

So radius=14/2=7 cm

Hence area of the circle=π × r^{2}**
**=22/7 × 7 ×7

=22 ×7

=154 sq cm

**Example 8.
**Find the area of the pentagon of the side 14 cm and apothem length 8 cm?

**Solution:**

Given pentagon side=14 cm,apothem length=8 cm

Area of the pentagon=5/2 ×s ×a

=5/2×14×8

=5×7×8

=280 sq cm

Hence, the area of the pentagon is 280 sq cm

**Example 9.
**Find the area of the regular hexagon whose side is 2 cm?

**Solution:**

Given side of the hexagon=2 cm

Area of the hexagon=3\(\sqrt{ 3}\)/2 s^{2}

=3\(\sqrt{ 3 }\)/2 2^{2}

=3\(\sqrt{ 3 }\) × 2

=6\(\sqrt{ 3 }\) sq cm

Therefore, Area of the regular hexagon is 6\(\sqrt{ 3 }\) sq cm.

**Example 10.
**Find the area of the pentagon of the side 12 cm and apothem length 4 cm?

**Solution:**

Given pentagon side=12 cm,apothem length=4 cm

Area of the pentagon=5/2 ×s ×a

=5/2×12×4

=5×6×4

=120 sq cm

Hence, the area of the pentagon is 120 sq cm
