Question

The breadth of a rectangular field is twice its length. If the area of the field is 1058m2, find the cost of fencing it at ₹35 per m.

Answer 1

Answer:

RS 74060

Step-by-step explanation:

let the length be X

breadth be 2X

so we know X × 2X = 1058

x2 = 1058/2

x2 = 529

X = √529

X = 23

so length is 23

breadth is 46

perimeter of the field = 2×( 23+46)

= 2116m

cost of fencing = 2116×35

= RS 74060
