Answer:
15m2
750 rupees
Step-by-step explanation:
GIVEN,
LENGTH OF THE POOL 15m
BREADTH OF THE POOL 7m
PATH 1m
AREA OF THE SWIMMING POOL = L×B
= 15×7 = 105m²
AREA OF THE SWIMMING POOL WITH THE PATH
= 15×8 (ADD THE 1M WITH THE BREADTH OF THE POOL 7+1)
= 120m²
NOW,
AREA OF THE PATH = (120-105)m²
= 15m² (ans)
COST OF CONSTRUCTING THE PATH = RS (15×50)
= 750 rupees (ans)
