Question 3.

Matthew is 6 feet 2 inches tall. His little cousin Emma is 3 feet 6 inches tall. How much taller is Matthew than Emma?

Answer:

The height of Matthew = 6 feet 2 inches Which means, 74 inches

The height of his little cousin Emma = 3 feet 6 inches Which means, 42 inches

Question 4.

In gym class, Jared climbed 10 feet 4 inches up a rope. Then, he continued to climb up another 3 feet 9 inches. How high did Jared climb?

Answer:

Given that,

Firstly,Jared climbed 10 feet 4 inches

The length he continued climbing = 3 feet 9 inches

Total length = 10 feet 4Â inches + 3 feet 9 inches = 13 feet and 13 inches

Also written as 14 feet 1 inch

Therefore, the total length Jared climbed = 14 feet 1 inch.

Question 5.

A quadrilateral has a perimeter of 18 feet 2 inches. The sum of three of the sides is 12 feet 4 inches.

a. What is the length of the fourth side?

b. An equilateral triangle has a side length equal to the fourth side of the quadrilateral. What is the perimeter of the triangle?

Answer:

a. Given , the parameter of quadrilateral = 18 feet 2 inches or 17 feet 14 inches

The sum of three of the sides = 12 feet 4 inches

The length of fourth side = 18 ft 2 in – 12 ft 4 in = 5 ft 10 in

Therefore, the length of forth side = 5 ft 10 in

b. The perimeter of triangle =

3 x (5 ft 10 in)

15 ft 30 inches

30 inches can also be written as 24 inches 6 inches

24 inches = 2 ft

Total = 17 ft 6 in

Therefore, the perimeter of triangle = 17 ft 6 in.

Question 3.

Laurie bought 9 feet 5 inches of blue ribbon. She also bought 6 feet 4 inches of green ribbon. How much ribbon did she buy altogether?

Answer:

Given that,

The length of blue ribbon Laurie bought = 9 feet 5 inches

The length of green ribbon Laurie bought = 6 feet 4 inches

Total length : 9 ft 5 in + 6 ft 4 in

= 15 ft 9 in

Question 4.

The length of the room is 11 feet 6 inches. The width of the room is 2 feet 9 inches shorter than the length. What is the width of the room?

Answer:

11 feet 6 inches can also be written as 10 feet 18 inches

Given that the width of the room is 2 feet 9 inches smaller than the length

Now, 10 feet 18 inches – 2 feet 9 inches

= 8 feet 9 inches

Therefore, the width of the room = 8 feet 9 inches.

Question 5.

Timâ€™s bedroom is 12 feet 6 inches wide. The perimeter of the rectangular-shaped bedroom is 50 feet.
