Question

find the side of squre park is 75 m.find the cost of grassing on it at the rate of Rs1.40 per m2​

Answer 1

area of square= (side)²=(75)²=5625

now rate of RS 1.40per m²=1.40×5625=7875

Answer 2

$\huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

$\tt Given \begin{cases} \sf{Side \: of \: square \: park \: is \: 75 \: m.} \\ \sf{Cost \: of \: grassing \: on \: it \: is \: Rs.\: 1.40 \: per \: m^2}\end{cases}$

_____________________________

To Find :

We have to find the cost of grassing on it

______________________________

Solution :

To do this question we have to find the area of square. As, We have to find the cost of grassing.

So,

$\Large{\star{\underline{\boxed{\sf{Area = (Side)^2}}}}}$

Area = (75)²

Area = 5,625 m²

$\rule{200}{2}$

Now, we have to find cost of grassing on it at the rate of Rs. 1.40 per m².

So, We will multiply the area of the square by 1.40

A.T.Q

Cost = 5625 * 1.40

Cost = Rs. 7,875

∴ Cost of grassing the square park of side 75 m at the rate of Rs. 1.40 per m² is Rs. 7,875.

$\Large{\star{\underline{\boxed{\sf{Cost = Rs. \: 7,875 }}}}}$

$\rule{200}{2}$
