the length of a rectangle is 5cm longer than twice the length of the width. if the perimeter of the rectangle is 88, what Is the width?

Respuesta :

width=x
length=2x+5
perimeter of a rectangle=2(length)+2(width)
We can suggest this equation:
88=2(2x+5)+2x

88=4x+10+2x
6x=88-10
6x=78
x=78/6
x=13

width=x=13
length=2x+5=2(13)+5=26+5=31

Answer: the width would be 13 cm.
