Question

The length of a rectangle is half the width. The area is 25. What’s the perimeter

Answer 1

Answer:

the perimeter is 30

Step-by-step explanation:

ok so lets say this

width= x

length= 2x

the area is

A= wl

or

25 = x(2x)

25= 2x^2

5 = x thats the width so we know that if we double that we get the legnth so

the legnth is 10

the perimeter is defined as:

2l +2w =p

insert the width and legnth

2(5) + 2(10) = p

10+ 20= p

p= 30
