Asked by Johnathen

the length of a rectangle is (x-3) inches long, and the width 3 2/5 inches. If the area is 15 3/10 square inches, write and solve an equation to find the length of the rectangle
Answered by John
(x -3)(3 2/5) = 15 3/10

(x-3) (17/5) = 153/10

(x-3) = (153/10)(5/17)

x-3 = 153/34

x-3 = 4 1/2

x = 7 1/2
