Question

rectangle has a length of 15 cm and a perimeter of 72 cm.



Which equation could be used to find the width of the rectangle?









A.

15w = 72








B.

w + 15 = 72








C.

2w + 15 = 72








D.

2w + 30 = 72

Answer 1

THe perimeter of a rectangle is P
P=2*Length + 2*Width

Answer 2

They told you the Length is 15, put that in there and simplify a little

Answer 3

D, since the formula to find perimeter is 2(width) + w(length)
And we know the length, which is 15. So we simplify it by reducing it to
2w+30=72

Answer 4

P=72
length = 15

P = 2*length + 2*Width

Answer 5

d?

Answer 6

Yes, it's D
