Question 1. Asked on :17 January 2019:08:47:48 AM
path 1m wide built along the border and inside a square garden of side 30m. find ;
[i] The area of the path.
[ii] the cost of planting grass in the remaining portion of the garden at the rate of Rs.40 per m2
-Added by Nitish kumar Mathematics » Perimeter And Area
Answer:
Let ABCD, the square garden of side= 30 m.
PQRS is the region inside the garden.
so,
PQ = (30 -1-1 ) = 28 m
also
PS = ( 30 – 1 – 1 ) = 28 m
(i) Area of the path = Area of ABCD – Area of PQRS
= [( 30 x 30) – (28 x 28)]
= 900 – 784
= 116 sq.m
(ii) Area of the remaining portion in which the grass is planted = Area of square PQRS
= 28 x 28
= 784 sq.m
cost of planting the grass in the region PQRS = area x cost = 764 x 40
=31,360
