Question

Answer 2

Solution:-

Area of the rectangle ABCD (1st Road) = 22*2.5 

= 55 sq 

Area of the rectangle EFGH (2nd Road) = 30*2.5 = 75 sq m

Area of the rectangle IJKL (Joint part where these two roads meet) = 2.5*2.5

= 6.25 sq m

Area of the cross roads = Area of the rectangle ABCD + Area of the rectangle EFGH - Area of the rectangle IJKL

= 55 + 75 - 6.25

= 130 - 6.25

Area of the cross roads = 123.75 sq m
