Question

The perimeter of a rectangle is 20 centimeters. The length is 6 centimeters. What is the area of the rectangle?

Answer 1

2x + 2y = 20
2(6) + 2y = 20
12 + 2y = 20
2y = 8
y = 4
width = 4

Area = 6 × 4
= 24 cm

Answer 2

Perimeter minus the length is 14, so 14 x 6 would equal the area. so the area of the rectangle is 84
