Question

A rectangle has an area of 864 square centimeters and a length of 24 centimeters. What is the width of the rectangle?

Answer 1

Area of a rectangle is
A= l*w
l - length
w-width

substituting the values given to you
864 = 24 *w

solving for width
dividing 24 to both sides

864/24 = 24/24 *w
24/24=1
864/24=w

i dont carry a calculator around, but thats how you solve the problem

Answer 2

The answer is D. 36, simply divide 864 by 24
