Question

A rectangle has side lengths of 5 centimeters and 3 centimeters. If the side lengths are doubled, will the area also double?

Answer 1

Hey user!

your answer is here..

I don't think that the area of the rectangle will also double if it's sides are doubled.

let us check :D

given :-

length of the rectangle = 5cm

breadth of the rectangle = 3cm

area of the rectangle = l × b

= 5 × 3

= 15 cm²

if the sides of the rectangle is doubled, then the length of the side will be :-

length = 5 × 2 = 10cm

breadth = 3 × 2 = 6cm

area of new rectangle = l × b

= 10 × 6

= 60 cm²

now, double of 15cm² = 15 × 2 = 30cm²

and the area of new rectangle is 60cm²

hence the area won't be double.

cheers!!
