length 70 m and breadth 50 m and parallel to its sides. Find the area of the roads. Also find the
area of the park excluding cross roads.​

Answer 1

Answer:

A and B are two roads in the park.

area covered by road A=700×10(m

2

)

=7000 m

2

area covered by road B=300×10 m

2

=3000 m

2

Common area covered by road A and B=10×10 m

2

=100 m

2

area covered by roads =7000 m

2

+3000 m

2

−100 m

2

=10000 m

2

−100m

2

=9900 m

2

=0.99 hectare

area of the park =700×300 m

2

=210000 m

2

area of the park encluding cross Road =210000 m

2

−9900 m

=20.01 hectare

Answer 2

Answer:

The area of the park is 3500 m
The area of the park excluding the roads is 2780 m

Step-by-step explanation:

Area of the park= 70*50= 3500 m

Area of the roads= (6*70)+(6*50)

= 420+300

= 720 m

Area of the park excluding roads = 3500 - 720

= 2780 m
