**Concepts and Skills**

Question 3.

Kevin has a rectangular rug that has a perimeter of 16 feet. Draw a rectangle that could represent Kevin’s rug.

Answer:

Explanation:

perimeter is 16 feet.

p = 2 (l + w)

16 = 2 (l + w)

l + w = 8

let us consider l = 3

and w = 5

3 + 5 = 8

Question 4.

**Use Tools** Pablo draws a rectangle that has a length of 3 feet and a width of 4 feet. Select all the rectangles that have the same area and a different perimeter. Tell what strategy and tool you will use to solve the problems, explain your choice, and then find the answers.

(A) length 6 feet, width 2 feet

(B) length 3 feet, width 3 feet

(C) length 7 feet, width 1 foot

(D) length 1 foot, width 12 feet

(E) length 2 feet, width 5 feet

Answer: A and D

Explanation:

length 6 feet, width 2 feet

area = l x w

= 6 x 2 = 12

p = 2 (l + w)

p = 2 x 8

= 16

length 1 foot, width 12 feet

area = l x w

= 1 x 12

= 12

p = 2 (l + w)

p = 2 x 13

p = 26

I have used the formula for finding the area and perimeter.

24 = 6s

s = 4

Question 8.

Dara wants to frame a rectangular painting that has an area less than 30 square inches. She has 20 inches of wood to make a frame. Draw a rectangle that could represent Dara’s painting.

20 = 2 (l + w)

l + w = 10

let us consider l = 3

and w = 7

3 + 7 = 10
