Question

A 20 cm × 15 cm paper was cut as shown in the figure. compare the perimeters and areas of both shapes.​

Answer 1

Answer:

First Figure,

Length is 15cm

Breadth is 20cm

So, Perimeter = 2(l+b)

                       = 2(15+20)

                       = 2X35

                       = 70

Area = l X b

        =15 X 20

        =300 cm^2

In the second figure,

Add the numbers and you will get the perimeter.
