Question

The area of a rectangle is 60 in² and the length of the rectangle is 7 in. 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?



w + 7w = 60

w(w+7)=60

7w = 60

w + 7 = 60

Answer 1

w(w+7)=60

Explanation:

Ideally,Area of a triangle is given by A=L×W ,where A= area, L=length and W= width

and from the expression the length is seven more than the width means :7+W

Also t from the expression

• The area of a rectangle is found by multiplying the length times the width
• makes the equation become

A= W(W+7)As the formula.
