Question

area of a rectangular plot is 880 m and its length is 44m fiend its perimeter also find the cost of fencing it at the rate of rs 5 per meter

Answer 1

In this question,
Area of rectangular plot = 880 m^2.
Length = 44 m
So, Breadth = 880/44 = 20 m .
Now, Perimeter = 2(l+b) = 2(44+20) = 2*64 = 128 m .
Cost of fencing = Rs 5 * 128 = Rs 640.

Answer 2

Correct question:-

Area of a rectangular plot of length 44m is 880m^2 . Find its preimeter.Also ,find the cost of fencing at the rate of ₹5 per meter.

_____________________________

▪Given that:-

• Length of rectangular plot= 44m.

• Area of rectangular plot= 880m^2.

• cost of fencing per metre= ₹5.

▪To find:-

• Perimeter of rectangular plot.

• Cost of fencing.

Area = length × Breadth.

880m^2 = 44m × Breadth

= 880/44 = 20m [Breadth]

●Perimeter of rectangular plot =

Perimeter = 2 × ( Length + Breadth )

Perimeter = 2 × ( 44 m + 20 m )

Perimeter = 2 × 64 m

Perimeter = 128 m.

●Cost of fencing rectangular plot =

Cost of Fencing = Perimeter × Cost.

Cost of Fencing = 128 m × Rs. 5

Cost of Fencing = Rs. 640

$\therefore$ Perimter of plot is 128m. and cost of fencing the plot is Rs. 640.
