Question

A square shaped garden with an area of 64 $c{m}^2$ has to be fenced across the boundary. Find the total cost of fencing if the rate of fencing is Rs 2 per metre.

• A. Rs. 32
• B. Rs. 64
• C. Rs. 108
• D. None of these

Answer 1

The correct option is B Rs. 64

Area of square = $(side{)}^2$
Area of the square = 64 $c{m}^2$
Therefore,
Side length = 8 cm
Total cost = (4 $\times$ 8) $\times$ Rs. 2
= Rs. 64
