Question

Find the area of the roads if two roads are running in cross section through the middle of the ground​

Answer 1

Step-by-step explanation:

Here, PQ=10m and PS=300m, EH=10m and EF=700m

And KL=10m and KN=10mArea of road in hectares, 1m  2

 

Area of roads = Area of PQRS+Area of EFGH−Area of KLMN

[∵ KLMN is taken twice, which is to be subtracted]

=PS×PQ+EF×EH−KL×KN

=(300×10)+(700×10)−(10×10)

=3000+7000−100

=9,900m 2

Area of road in hectares, 1m2 =1/10000 hectares
