Question

the ratio of the lengths of the corresponding sides of two rectangles is 8:3. The area of the larger rectangle is 320 ft^2.  What is the area of the smaller rectangle?

Henry · Accepted Answer

8/3 = sqrt(320)/sqrt(A2) Cross multiply: 8*sqrt(A2) = 3*sqrt(320) Divide both sides by 8: sqrt(A2) = 3*sqrt(320) / 8 Square both sides: A2 = 45 Ft.^2.
