Question

length and breadth of a rectangle is 30 cm and 15 CM a part of 2.5 runs all around on outside find the area of the path​

Answer 1

let PQRS be the rectangular garden and ABCD internal boundry of the path.

length AB = 30 cm

breadth BC =15 cm

area of rectangle ABCD = AB x BC =30 cm x 15 cm = 450 cm^ 2

length= 30 cm - 2.5 cm -2.5 cm

25 cm

breadth = 15 cm - 2.5 cm - 2.5 cm

10 cm

area of rectangle EFGH = EF xFG =25 cm x 10 cm = 250 cm^2

area of path = area of rectangle ABCD - area of rectangle EFGH

450 cm^ 2 - 250 cm^ 2

200 cm^ 2
