Question

The area of a rectangle is 48 cm² and the length of the rectangle is 8 cm longer than the width. The area of a rectangle is found by multiplying the length times the width. During the Set Up step of the five-step problem-solving plan, which equation would you set up to solve for the width?

A. w(w+8)=48
B. w + 8 = 48
C. w + 8w = 48
D. 8w = 48

Answer 1

I believe the answer is A

Answer 2

Option A.

Explanation:

Let the length of a rectangle is l and width of the rectangle is w,

Then as per statement " Length of the rectangle is 8 cm longer than the width"

l = w + 8

Now we know area of a rectangle is represented by the formula

Area = Length × width

Area = l × w

= (w + 8)w

Area of the rectangle has been given as 48 cm² then the formula will be

w(w + 8) = 48

Option A is the answer.
