Question

A rectangle has a width of 46 centimeters and a perimeter of 204 centimeters. What is the rectangle’s length?

Answer 1

Length = 56

Explanation:

Perimeter = Length + Length + Width + Width

Perimeter = 2L + 2W

2L + 2W = 204

2L + 2(46) = 204

2L + 92 = 204

Subtract 92 from both sides

2L = 112

Divide both sides by 2

L = 56

Length = 56
