Q10 of 97 Page 780

A rectangular park 35 m long and 18 m wide is to be covered with grass, leaving 2.5 m uncovered all around it. Find the area to be laid with grass.

Given:


Length of park = 35 m


Breadth of park = 18 m



Now,


Length to be covered = 35 – (2.5 + 2.5)


= 30 m


Breadth to be covered = 18 – (2.5 + 2.5)


= 13 m


Area of park = Length × Breadth


= 30 m × 13 m


= 390 m2
