Question

In the given figure, find the area of the path (shaded portion) which is 2 m wide all around.
40 m​

Answer 1

Answer:

384 m²

Step-by-step explanation:

Inner Length = 60-4 = 56m

Inner Width = 40-4 = 36m

Area of shaded portion = 60*40 - 56*36

= 2400 - 2016

= 384 m²

Answer 2

Answer:

area of outer rectangle is 40m*60m=2400m^2

to find the area of inner rectangle we need to know the length and breadth

length will be 60m -(2m+2m)=56m we have to substract the width of the path from both side same yoy have to do for breath also so, breadth will be 40m-(2m+2m)=36m

so,

the area of inner rectangle = 56m *36m

=2016m^2

the area of the shaded portion or path will be=

Area of the outer rectangle - Area of inner rectangle=(2400-2016)m^2

=384m^2
