Question

A rectangle has a perimeter of 50 meters. Side A is 5 meters longer than side B. What are the lengths of side A and side B

Answer 1

Let's say that a=the length of the rectangle and b = the width. But a = b+5 so the rectangle has perimeter 2(a +b) = 50

a+b = 25

b+5 + b = 25

2b = 10

b=10; a= 15.

 

A rectangle is named by its four vertices (points), e.g. ABCD. It's not a good convention to use capital letters the way you did; you can refer to length AB and width BC, however.
