Question

Q4 A rectangular piece of land
measures 18 m by 12.5m. It is to be
fenced with five rows of wire all
along its four sides, find the cost of
fencing if one m of wire costs * 24.​

Answer 1

Step-by-step explanation:

$perimeter \: of \: rectangle = 2(l + b)$

$= 2(18 + 12.5) = 2 \times 30.5 = 61m$

it is to be fenced 5times

so length= 61 ❌ 5=305m

cost of 305 m= 305 ❌ 24= Rs 7320
