Find the length of a rectangular table if the perimeter is $95$ cm and width is $42$ cm. Find the cost of fencing a square field of each side $12$ m at a rate of Rs. $125$ per m?

Open in App

Solution

Perimeter of rectangular table = 95 cm
$2 (l + b) = 95$
$2 (l + 42) = 95$
$2 l + 84 = 95$
$2 l = 11$
$l = \frac{11}{2}$

Side of square field = 12 m
Perimeter = $12 \times 4 = 48 m$
Cost of fencing = $125 \times 48 = 6000$ Rs.
