Question

a narrow rectangular mural is 5 feet wide. it is 4 times as long as it is wide. find the perimeter and area of the mural. 20 ft 5 ft 5 ft 5 ft 5 ft 5 ft the perimeter of the mural is feet. the area of the mural is square feet.

Explanation:

Step1: Determine the length of the rectangle

Given width $w = 5$ ft and length $l=4\times w$. So $l = 4\times5=20$ ft.

Step2: Calculate the perimeter of the rectangle

The perimeter formula of a rectangle is $P = 2(l + w)$. Substitute $l = 20$ ft and $w = 5$ ft into the formula: $P=2(20 + 5)=2\times25 = 50$ ft.

Step3: Calculate the area of the rectangle

The area formula of a rectangle is $A=l\times w$. Substitute $l = 20$ ft and $w = 5$ ft into the formula: $A = 20\times5=100$ square - ft.

Answer:

The perimeter of the mural is 50 feet.
The area of the mural is 100 square feet.
