Question

The perimeter of a rectangle is 48 centimeters. The relationship between the length, the width, and the perimeter of the rectangle can be described with the equation 2⋅length+2⋅width=48. Find the length, in centimeters, if the width is 10 centimeters

Answer 1

The length of the rectangle is 14 cm

Explanation:

Here, we want to find the length of the rectangle given the width

Mathematically, the perimeter of the rectangle can be calculated using the formula;

2( l + w)

from the question w = 10

and perimeter = 48

Thus;

2( l + 10) = 48

divide both sides by 2

l + 10 = 48/2

l + 10 = 24

l = 24 - 10

l = 14 cm
