Question

A rectangle has a width of 51 centimeters and a perimeter of 210 centimeters. What is the rectangle's length?

The length is
cm.

Answer 1

Answer: 54 cm

Explanation:

Length is x

Perimeter = 2w+2l

Perimeter= 2(51)+2(x)=210

Perimeter=102+2x=210

Perimeter=2x=210-102

Perimeter=2x=108

Length= 54 cm

Answer 2

51*2=102. 210-102=108. 108/2=54.

The length is 54.
