Question

The perimeter of a rectangle is 64 cm. The length is 15 cm, how wide is rectangle?

Answer 1

17 cm

Explanation:

Rectangle perimeter: length*2 + width*2

Substitute width with "x".

Length is given as 15 cm

Perimeter is given as 64 cm

Plug in the values and solve for x.

64 = 2*15 + 2x

64 = 30+2x

2x = 34

x = 17

so width is 17 cm

Answer 2

The width is 17 centimeters
