Circle requires ≈ 20 m of edging
Step-by-step explanation:
A = πR²
R = √(A/π)
C = 2πR = 2π√(A/π)
C = 2π√(30/π) = 19.41625... ≈ 20 m
square needs ≈ 22 m of edging
equilateral triangle needs ≈ 25 m of edging
Given :-
- The price of a telephone reduced form Rs 3500 to Rs 3200.

→ Decrease = Rs 300
Now we may find the % change in its price by ,
→ Decrease in cost/Initial cost * 100 %
→ Rs 300 /Rs 3500 * 100 %
→ 8.57%
