Question

Write the algebraic expression for:

(i) The area of a reactangle if its length (l) is increased by 5 and breadth (b) is reduced by 3.

(ii) Volume of a cubiod if its length (l) is reduced by 7, height (h) becomes 3 times and width (w) is increased by 2.

Solution

(i) Area of a rectangle = length × breadth

new length = l + 5

new breadth = b - 3

So, new area = (l + 5)(b - 3)


(ii) Volume of cuboid = length × height × width

new length = l - 7

new height = 3h

new width = w + 2

So, new volume = (l - 7)(3h)(w + 2)
