The formula for the perimeter of a rectangle is P = 2l + 2w. Find w if P = 68 and l = 10.

Any ideas?

OpenStudy (harsimran_hs4):

you are given the values for P and L and you have a equation P = 2l + 2w so substitute the values of P and L and try to find the answer

OpenStudy (anonymous):

W = 15?

OpenStudy (skullpatrol):

Substitute that value into your equation and check to see if you get a true statement.

OpenStudy (harsimran_hs4):

@obeynicole your answer is incorrect show us what you did (step by step)

OpenStudy (anonymous):

W = 28 i think i did it right this time, i did it on paper.

OpenStudy (harsimran_hs4):

OpenStudy (anonymous):
