Question

answer my question please



find the cost of cultivating a rectangular field 35 metre long and 18 metre wide at rupees 20 per square metre also find the cost of fencing the field at rupees 15 per metre ​

Answer 1

Answer:

cultivating land area =35*18=630m²

price=630*20=1260

Step-by-step explanation:

fencing field perimeter=2(35+18)

=2*53

=106

fencing cost=106*15=1590

Answer 2

Answers

✩ The Cost of Cultivating the Field = ₹12600.

✩ The Cost of Fencing the Field = ₹1590.

STEP WISE SOLUTION

Given:-

Length (l) of the Rectangular Field = 35m.

Breadth (b) of the Rectangular Field = 18m.

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 35m}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 18m}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$

To Find :-

1) The cost of cultivating the field at rate of ₹20 per m².

2) The cost of fencing the field at ₹15 per meter ​.

ANSWERS

1) Cost of cultivating

To Find the cost of cultivating , first we must find out the area of the rectangle.

Area of Rectangle = Length(l) × Breadth(b)

Here ,

Length (l) of the Rectangular Field = 35m.

Breadth (b) of the Rectangular Field = 18m.

$\implies$

Area of the Rectangular Field = 35 × 18

$\implies$

Area of the Rectangular Field = 630 m².

$\boxed{\sf Cost \: of \:Cultivating\: the \: field = Area \:of \:the\: field * Rate \:of \:Cultivation}$

∴ Cost of Cultivating the Field = 630 × 20

✳ The Cost of Cultivating the Field = ₹12600.

2) The Cost of Fencing

To Find the cost of Fencing , first we must find out the perimeter of the rectangular field.

Perimeter of Rectangle = 2(Length × Breadth) = 2(l+b)

Here,

Length = 35m.

Breadth = 18m.

∴ Perimeter of the Rectangular Field = 2(35+18)

$\implies$

Perimeter of the Rectangular Field = 2 × 53

$\implies$

Perimeter of the Rectangular Field = 106 m.

$\boxed{\sf Cost \: of \:Fencing\: the \: field = Perimeter \:of \:the\: field * Rate \:of \:Fencing}$

$\implies$

Cost of Fencing = 106 × 15

✳ The Cost of Fencing the Field = ₹1590
