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?
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
Now, the age difference = 6 ft 2 in – 3 ft 6 in = 2 ft 8 in
Therefore, the Mathew is 2 feet 8 inches than Emma.

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?
Given that,
Firstly,Jared climbed 10 feet 4 inches
The length he continued climbing = 3 feet 9 inches
Total length = 10 feet 4  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?
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?
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
Therefore, the total length of ribbons Laurie bought altogether = 15 feet 9 inches.

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?
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.
