the width of a rectangle is 1/2 of its lengh what are the sides of the rectangle if its perminiter is 63 in. Please put the right answer and not the wrong answer i will also give brainly to someone if you do it correctly

Respuesta :

Let's take length = x, width = 1/2x.

Perimeter of a rectangle is = 2(L + W)

So, 63 = 2(x + 1/2x),
Expand: 63 = 2x + 2/2x
63 = 3x, x = 21

Therefore, length = 21 in and width = 10.5 in

Check answer 2(21+10.5) = 63
