Answers
Step-by-step explanation:
₹7200 is the cost of fencing the rectangular park.
★ Given:
Length of the rectangular park = 225 m
Breadth of the rectangular park = 175 m
Rate of fencing per metre square =Rs 15
★ To Find:
The total cost of fencing the rectangular park.
★ Analysis:
In this question, we have to first find the perimeter of the park and then multiply it with the cost of fencing for 1 m².
★ Solution:
Perimeter of the rectangular park = 2 (l +b)
Substituting the values:
2 (225 + 175)
= 2 x 400
= 800 m
Cost of fencing the complete perimeter of the ground = Cost of fencing for 1 metre square x Total perimeter
= 15 x 800
= Rs 12000
∴ The amount to paid for fencing the perimeter of the ground is Rs 12000.
Important Perimeter Formulae:
→ Perimeter of rectangle = 2 (l + b)
→ Perimeter of square = 4a
→ Perimeter of triangle = a + a + a (or) a + b + c
→ Perimeter of circle = 2πr
