Question

The length of a rectangle is 5 cm longer that twice the width. If the total perimeter is 88 cm, what is the length and width?

Answer 1

an equation you could use to find the length would be 2x+5. The width would be x. In order to find the perimeter:

2(2x+5) + 2(x)=88
4x+10+2x=88
6x+10=88
6x=78
x=13
The width is 13 since it is x and if we plug 13 into the equation 2x+5, the length would be 31.
