Area of a rectangle with length 4ab and breadth 6b² is
(a) 24a²b²
(b) 24ab³
(c) 24ab²
(d) 24ab

Solution:

Correct option is (b).

Area of the rectangle = length × breadth

Given length 4ab and breadth 6b²

∴ Area of the rectangle = 4ab × 6b² = 24 a (b × b²)

= 24 ab³

✦ Try This: The area of the rectangle with length (x + 2y) and breadth x is _______?

Solution: Area of the rectangle = length × breadth

Given length (x + 2y) and breadth x

∴ Area of the rectangle = (x + 2y) × x = x² + 2xy
