Question

1. Two cross-roads each 1,5 m wide run at right angles through the centre of a square park of side
60 m, such that each is parallel to one side. Find the area of the remaining portion of the
park.​

Answer 1

Answer:

3422.25 sq-m

Step-by-step explanation:

Area of park = 60x60 = 3600 m^2

Area of each road of width 1.5m and length 60m = 60x1.5= 90 m^2

While considering total area of roads = 2x 90 = 180 m^2, the four-way in middle of park is considered twice.

So net area of roads = 180-1.5x1.5 = 177.75 m^2

Remaining area = 3600-177.75 =3422.25 sq-m
