Question

9. In the adjoining figure, find the area of the path (shown
shaded) which is 2 m wide all around.

length = 100m.
Breadth = 60m.​​

Answer 1

Area of path= 2(lb+bh+lh)


2(100*60+60*2+2*100)

2(6000+120+200)

2(6320)

2*6320

= 12640m^2

Answer 2

Answer:

Step-by-step explanation:

AREA OF RECTANGULAR FIGURE=LENGTH X BREADTH

MEASUREMENTS WITH SHADED PART :

LENGTH =100m    }GIVEN

BREADTH=60m    }GIVEN

AREA WITH SHDED PART = 100X60=6,000m ²

AREA  WITHOUT SHADED PART={100-2}x{60-2}=5684m²

area of shaded part =area of fig.-area without shaded part

AREA OF SHADED PART=6,000-5,684m²

AREA OF SHADED PART=316m²

HOPE YOU FIND IT CORRECT ,

AND MAKE IT THE BRAINLIEST!!!!!!!!!!!!!!!
