Problema Solution
A table top is shaped like a rectangle whose perimeter is 78.4in. The length is 7.2in. more than the width. Find the length and the width
Answer provided by our tutors
perimeter = 2*length + 2*width
Let 'w' represent the width, then 'w+7.2' represents the length
78.4 = 2w + 2(w+7.2)
-------------------------
-------------------------
w=16
16+7.2 = 23.2
The width is 16 in., the length is 23.2 in.
