Question

A square crop is there it has one road around the crop and the road's wide is 2metre and the area of road is 416sq.m what is the area of the crop.​

Answer 1

Step-by-step explanation:

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

And KL=10m and KN=10m

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

=9,900m2

Area of road in hectares, 1m2=100001hectares

∴9,900m2=100009900=0.99 hectares

Now, Area of park excluding cross roads = Area of park−Area of road

=(AB×AD)−9,900

=(700×300)−9,900

=2,10,000−9,900

=2,00,100 m2

=10000200100 hectares=20.01 hectares.
