95/2.1 the length of a rectangular poster is 10 inches longer than the width. if the perimeter of the poster is 124 inches, what is the width?

So basically I let length = w + 10

perimeter = 124

therefore, w+w+w+10+w+10 = 124

will give you, 4w + 20 = 124

then subtract, 4w = 124 - 20

then divide, w = 104 / 4

results,. w = 26 inches.

in conclusion, width = 26inches and

length = 26 + 10 = 36inches.
