Answers
Answer
- Cost will be ₹997.5
Explanation
Given
- Length of ground = 28 m
- Breadth of ground = 15 m
- Width of gallery = 5 m
To Find
- Cost of making that gallery at Rs.5.25 per square metre
Solution
✭ Area of ground
→ Area of ground = Length×Breadth
→ 28 × 15
→ Area of ground = 420 m²
✭ Area of the remaining part
→ (28 - 5)( 15 - 5)
→ 23×10
→ 230 m²
✭ Area of gallery
→ Area of gallery = Area of ground - Area of the remaining part
→ Area of gallery = 420 - 230
→ Area of gallery = 190 m²
✭ Cost of making the gallery
→ 190 × 5.25
→ Rs.997.5
Answer:
- Area of the spectator gallery = 530 m²
- The cost of making that gallery = 2782.50 rs.
Step-by-step explanation:
- Area of basketball ground = 28 x 15
= 420 m²
- Total Area (basketball ground + spectators gallery)
= (28+5+5) x (15+5+5)
= 38 x 25
= 950 m²
- area of spectators gallery = 950 - 420
= 530 m
the spectator gallery and the cost of making that gallery at rs. 5.25 per square meter(Given)
- The cost of making that gallery = 530 x 5.25
= 2782.50 rs.
