Question

The LEngth of a Rectangle is twice its width. Its perimeter is 15 inches, what is the area of the Rectangle?

Answer 1

2x (width) + 2y(length) = 15..... length is twice its width so 2x + 2(2x) = 15
2x+4x = 15
6x = 15
x = 15/6

Answer 2

We have here that L=2W

L being length and W being Width.

Perimeter is 2L+2W

so 15=2L+2W
but we know that L= 2W so
15=2(2W)+2W

so then 15=4W+2W or 15=6W
so then W=15/6.
and since L=2W

L=2(15/6) = 30/6 = 5

and the area is = L* W which we now know, so all you do is multiply

Answer 3

I hadn't seen that you had posted it up already -_- lol

Answer 4

juan_9292 is more complete though, I didn't notice the area was required as well.

Answer 5

so whats the Area then? O.o confused

Answer 6

Well since by solving for W and later on for L
we got that

W=15/6
L=5

so for area all you have to do is Multiply L X W

Answer 7

it must b wrong then my answer choices are { f:7.5, G: 12.5 , H:15, i:25.}

Answer 8

no, its right;

Answer 9

which that is = 12.5
