Answer 1

CORRECTED QUESTION

What is the expenditure of leveling a square ground with side 80 m at

₹15 per m² ?

Answer:

$\red\bigstar$ Expenditure of leveling the square ground = ₹96,000.

SOLUTION

Sides of the square ground = 80m.

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(4,0){2}{\line(0,1){4}}\multiput(0,0)(0,4){2}{\line(1,0){4}}\put(-0.5,-0.5){\bf D}\put(-0.5,4.2){\bf A}\put(4.2,-0.5){\bf C}\put(4.2,4.2){\bf B}\put(1.5,-0.6){\bf\large 80m}\put(4.4,2){\bf\large 80m}\end{picture}$

We know that leveling is done inside the perimeter , we must find the area of the ground.

Area of a square = a², Where a is the side of the square.

Here,

a = 80m.

⇒ Area of the square ground = 80²

⇒ Area of the square ground = 6400 m²

$\boxed{\sf Expenditure\: of\: leveling\: the \:field = Area \:of \:the\: field * Rate\: of \:leveling}$

Rate of leveling = ₹ 15 /m²

⇒ Expenditure of leveling the square ground = 6400 × 15

⇒ Expenditure of leveling the square ground = ₹96,000.

Answer 2

Answer:

Cost of levelling is = ₹96,000

Step-by-step explanation:

Question -

What is the expenditure of levelling a square ground with side 80 m at ₹15 per m²?

ㅤ

Solution -

• Let's find the area of the square ground prior the cost of levelling.

$\color{black}\boxed{\colorbox{saffron}{Area - side×side}}$

$80 \times 80 \\ \\ = 6400 {m}^{2}$

So, area is 6400 m².

ㅤ

• ㅤNow, let's find the required cost for levelling the square park.

$= 6400×15 \\ \\ = ₹96,000$

So, cost of levelling 6400 m² is ₹96,000.
