If the length is 8 feet, perimeter is 24 feet, what is the width and area?

Question

Need to find the area if the lenght is 8 feet and perimeter is 24 feet.  The width and area are unknown.

Answer 1

Area of rectangle(A) = l*b

Perimeter of rectangle (P) = 2(l+b)

Given P = 24feet and l = 8feet.

2(8+b) = 24

Divide to each side by 2.

8+b = 12

Subtract 8 from each side.

b = 4

Area = 8*4 = 32 Squre feet.

Rectangle Width is 4 feet and area is 32 feet^2.
