Question

The cost find the cost of fencing of a rectangular field of length 50 M and breadth 42m at the rate 8 per m

Answer 1

50 + 50 = 100

42 + 42 = 84

184 m x 8 = 1472

The cost of the fencing is 1472.

Answer 2

Length = 50m

Breadth = 42m

Perimeter of rectangular field = 2×(length + breadth)

=2×(50+42)

= 2×(92)

=184 m

Cost of fencing 1m of the field = rs. 8

Cost of fencing 184 m of the field = 184 × 8

=Rs. 1,472
