The perimeter of rectangular photo is 72cm. the length is twice the width what are and width of the photo?
(hint: the formula for perimeter is 2w+ 21= p where w is the width i is the length and p is the perimeter.)

w =12 cm

l = 24 cm

Step-by-step explanation:

P = 2w + 2l

We know the perimeter is 72 and the length is twice the width (l = 2w)

Substituting P = 72 and l = 2w

72 = 2w + 2(2w)

72 = 2w+ 4w

Combine like terms

72 = 6w

Divide each side by 6

72/6 =6w/6

12 = w

Now we need to find l

l = 2w

l =2*12

l = 24
