Question

The area of a rectangular field is 768 m and its length is 32 m. Find
(i) the breadth of the field
(ii) the cost of fencing it at 20 per metre.​

Answer 1

Answer:

112m, 2240/-

Step-by-step explanation:

i)Breadth = Area/Length

= 768/32

=24m

ii)Now perimeter = 2 ( length + breadth)

= 2(24+32)

=112m

Therefore cost= rate x perimeter

= 20 x 112

=2240/-

Answer 2

Answer:

24m

Step-by-step explanation:

Area = Length * Breadth

So Breadth= Area / length

so Breadth= 768/32

So Breadth= 24m...... Ans
