The perimeter of a rectangle is 53 meters. The length is 2.3 meters longer than the width, w.

Question

Which equation below can you use to solve for the width, w, of this rectangle?

A. 2w + 2w + 2.3 = 53

B. 2(2w) + 2.3w + 53

C. 2w + 2(w + 2.3) = 53

D. 2w + 2(w - 2.3) = 53

Answer 1

both A and C are correct. They're equivalent.

Perimeter is 2 times the sum of length & witdth

both A and C have 2 times L+W or 2L + 2W = 53 with L replaced by W+2.3

B and D are incorrect
