Question

which of the following has larger area and by how much? A rectangle of length 52cm and breadth 38cms or a square of side 39cms​

Answer 1

Answer:

Rectangle

Step-by-step explanation:

rectangle=2xl+b

              =2x52+38    

             = 148

square=sx4

          =39x4=156

Answer 2

In rectangle : l = 52cm and b = 38cm

Area of rectangle = 2(l + b) = 2(52 + 38) = 180cm^2

In square : side = 39cm

Area of square = side ×4 = 39 × 4 = 156cm^2

area of rectangle - area of square

= 180 - 156 = 24cm^2

so, rectangle has larger area and by 24cm^2.
