Question

There are two cross roads,each of width 4m ruñning at right angles and parallel to the sides of a square park of side 72m.find the area of the park.

Answer 1

Answer:

Step-by-step explanation:

Each sides of the square park measure = 72 m

We know, area of square = s^2    or      s x s  ( s square)

           = 72^2 or 72 X 72

           = 5184 sq. m

Answer 2

Answer:

70,000

Step-by-step explanation:

Area of the crossroads, is equal to the area of the shaded portion in the figure.

Area of the shaded portion

=Area of the rectangle EFGH + Area of the rectangle IJKL - Area of the square PQRS

Area of the rectangle EFGH

= length×breadth = 72×4 = 288sq.m

Area of the rectangle IJKL

= length×breath = 72×4 = 288sq.m

Area of square PQRS

= side×side = 4×4 = 16sq.m

The cost of paving tiles

= 560×125 = 70,000
