Question

A rectangular plot of land is 240 m by 200m the cost of fencing per meter is rs. 30 what is the cost of fencing the entire field

Answer 1

Length of the fence = Perimeter of the rectangular plot
= 2 ( I + b )
= 2 (200 + 240)
= 2 * 440
= 880 m.
Cost of fence = 880 * 30= rupees 26400

Answer 2

Answer:

$Cost\: of fencing \:the\\ \:entire\:field \: </p><p>= Rs\: 26,400$

Step-by-step explanation:

$Dimensions\: of \: a \\\: rectangular \: plot \: of \: land :</p><p>$

$Length (l) = 240\: m ,\\ breadth (b) = 200\: m$

\* we know that,

Perimeter of a rectangle (P) = 2(l+b) */

P = 2(240m+200m)

=> P = 2×440m

=> P = 880 m ---(1)

$Cost\: of fencing \\\:one \: meter\:field \: = Rs\: 30$

/* given */

Now ,

$Cost\: of fencing \:the\\ \:entire\:field \: = 880 \times \: 30$

= $Rs\: 26,400$
