Question

A rectangle is (8x + 4y) cm long and (7x + 2y) cm broad. Find its area​

Answer 1

Answer:

Length of the rectangle = (8x + 5) cm Breadth of the rectangle = (5x + 3) cm ∴ Area of the rectangle = length × breadth = (8x + 5) × (5x + 3) = 8x × (5x + 3) + 5 × (5x + 3) = (8x × 5x) + (8x × 3) + (5 × 5x) + (5 × 3) = 40x² + 24x + 25x + 15 = 40x² + 49x + 15 ∴ The area of the rectangle is (40x² + 49x + 15) sq. cm.Read more on Sarthaks.com - https://www.sarthaks.com/861016/a-rectangle-is-8x-5-cm-long-and-5x-3-cm-broad-find-its-area
