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

Option A.

Step-by-step 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.

associative property of multiplication

answer: it's d
