Question

Area of the rectangular field is 456 sq. m. If the breadth of the field is 12m.

Find the length of the field. Also find the cost of fencing if the cost of fencing

per m is Rs. 150.​

Answer 1

Step-by-step explanation:

Given:-

Area of rectangle = 456 sq.m

Breadth = 12 m.

Length = ?

Rate = 150

Area = length × breadth

456 = length × 12

length = 456 ÷ 12

length = 38 m.

Perimeter of rectangle = 2 × ( length + breadth)

= 2 × ( 12 + 38 )

= 2 × 50

= 100 cm.

Cost of fencing = perimeter × rate per metre.

= 100 × 150

= 15000 Rs.

Therefore, the cost of fencing is 15000 Rs.
