Question

Do you links of a rectangle is for X +7 and the width is three if the area of the rectangle is 129 square units what is the value of X

Answer 1

x = 36

Explanation:

Length of a rectangle, x+7

Width = 3

Area of the rectangle, A = 129 units²

The area of a rectangle is given by :

A = lb

So,

`(x+7)* 3=129\\\\(x+7)=43\\\\x=43-7\\\\x=36`

So, the value of x is equal to 36.
