AREA OF LAWN =75×60
=4500
THEN FIND AREA OF SWIMMINGPOOL
20×7
=140
THEN SUBTRACT THE AREA OF LAWN AND AREA OF SWIMMING POOL
=4500-140
=4360
45 PER Sq METER
4360×45
=196200
Answer:
1800₹
Explanation:
ABCD is the lawn
EFGH is the swimming pool
(so we are supposed to find the area of the lawn without swimming pool, or area of lawn - area of swimming pool)
.°. Area of lawn = 75×60
(L's Area) = 450 m²
Now, Area of swimming pool = 20×7
(P's area) = 140 m²
so,
L's area - P's area
= 450-140
= 310m²
so the area, of the ground where the grass is supposed to be grown is 310m².
A.T.Q
Cost of growing grass in 1m² = 45
.°. cost of growing grass in 310 m² = 45×310
= 1800 ₹
