Answer:
Total cost for curtains = Rs.3,700
Explanation:
Assume we have:
1 Door ( l = 8ft, b=4ft)
3 Windows (l = 4t, b = 3.5ft)
Curtains at the rate of Rs.50 per ft²
Find:
Total cost for curtains.
Computation:
Area of door = (8)(4)
Area of door = 32 ft²
Area of 3 windows = (3)(4)(3.5)
Area of 3 windows = 42 ft²
Total ares = Area of door + Area of 3 windows
Total ares = 32 ft² + 42 ft²
Total ares = 74 ft²
Total cost for curtains = Rs.50 × Total ares
Total cost for curtains = Rs.50 × 74 ft²
Total cost for curtains = Rs.3,700
