Solve the following problems. Use pictures, numbers, or words to show your work.

Question 1. The rectangular projection screen in the school auditorium is 5 times as long and 5 times as wide as the rectangular screen in the library. The screen in the library is 4 feet long with a perimeter of 14 feet. What is the perimeter of the screen in the auditorium? Answer: The perimeter of the screen in the auditorium is 70 feet,

Explanation: Given the rectangular projection screen in the school auditorium is 5 times as long and 5 times as wide as the rectangular screen in the library. The screen in the library is 4 feet long with a perimeter of 14 feet. Let wide of of screen in library be w feet, so 14 feet = 2 X (4 feet + w feet), 14 feet = 8 feet + 2 X w feet, 2 X w feet = 14 feet – 8 feet = 6 feet, So wide = 6 feet ÷ 2 = 3 feet, Now the rectangular projection screen in the school auditorium is 5 X 4 feet = 20 feet long and wide is 5 X 3 feet = 15 feet wide, So the perimeter of the screen in the auditorium is 2 X (20 feet + 15 feet) = 2 X 35 feet = 70 feet.

Question 2. The width of David’s rectangular tent is 5 feet. The length is twice the width. David’s rectangular air mattress measures 3 feet by 6 feet. If David puts the air mattress in the tent, how many square feet of floor space will be available for the rest of his things? Answer: 32 square feet of floor space will be available for the rest of his things,

Explanation: Given the width of David’s rectangular tent is 5 feet. The length is twice the width. David’s rectangular air mattress measures 3 feet by 6 feet. Area of the rectangular tent is 5 feet X ( 2 X 5 feet) = 5 feet X 10 feet = 50 square feet, now David’s rectangular air mattress area is 3 feet x 6 feet = 18 square feet, If David puts the air mattress in the tent, number of square feet of floor space will be available for the rest of his things is 50 square feet – 18 square feet = 32 square feet.

Question 3. Jackson’s rectangular bedroom has an area of 90 square feet. The area of his bedroom is 9 times that of his rectangular closet. If the closet is 2 feet wide, what is its length? Answer: The closet length is 5 feet,

Explanation: Given Jackson’s rectangular bedroom has an area of 90 square feet. The area of his bedroom is 9 times that of his rectangular closet. So closet area is 90 X feet X feet ÷ 9 = 10 square feet, As given closet is 2 feet wide, the length will be 10 feet X feet = 2 feet X length of the closet, length of the closet = 10 feet x feet ÷ 2 feet = 5 feet. therefore the length of the closer is 5 feet.

Question 4. The length of a rectangular deck is 4 times its width. If the deck’s perimeter is 30 feet, what is the deck’s area? Answer: The area of the deck is 36 square feet,

Explanation: Given the length of a rectangular deck is 4 times its width. If the deck’s perimeter is 30 feet, then 30 feet = 2 X (4 X width + width) , 30 feet ÷ 2 = 5 X width, 15 feet = 5 width therefore width = 15 feet ÷ 5 = 3 feet and length = 4 X 3 feet = 12 feet, Now the area of the deck is 12 feet X 3 feet = 36 square feet.
