Question

The cost of fencing a rectangular field at Rs.
40 per metre is Rs. 3200. If the length of the
field is 24m, then its breadth is
(a) 8 m
(b) 16 m
(c) 18 m
(d) 24 m

Answer 1

Answer:

16M

Step-by-step explanation:

IN ORDER TO FIND FENCE, FIRST FIND THE PERIMETER.

3200/40 = 80

THEREFORE, PERIMETER IS 80.

PERIMETER OF RECTANGLE = 2 X (L+B)

80 = 2 X (24 + B)

80/2 = 24+ B

40 = 24+B

B = 40-24

B = 16M
