Question

The area of rectangular field is 768sq m and it's length is 32m.
Find
1. it's breadth
2. the cost of fencing it at rs.20 per metre​

Answer 1

Step-by-step explanation:

Given that:

Length of a rectangle field =3x

Breadth of a rectangle field =2x

Area =3456 m 2

3x×2x=3456 m 2

6x 2 =3456 m 2

x 2 =576 m 2

x=24 m

Therefore, the length =72 m

Breadth =48 m

Perimeter of the rectangular field =72+48=120 m

Cost of 1 meter =Rs.4

Cost of 120 meter =Rs.4×120=Rs.480.

This is the required solution.

Answer 2

1.

Since area of rectangle is length into breadth. So lets the breadth be b.

area = lxb

768 = 32xb

24 = b

The breadth of the rectangular field is 24 metre.

2.

total cost of fencing = area x cost of fencing at per metre.

.

. . T = 768 x 20

T = RS 15360

The Total Cost of Fencing is a RUPEE 15360.
