Question

What is the area of the square park whose side is 120 meters? Find the cost of planting the

grass at Rs 12 per square meter.​

Answer 1

Answer:

14400m^2

Price- Rs 172800

Step-by-step explanation:

See Area of square is side*side

After Finding the area with this method multiply it by the cost of painting per meter square.

Answer 2

$\large \underline{\underline{\tt Given}} :$

• Side of square park = 120 m
• Cost of planting grass per m² = Rs. 12

$\large \underline{\underline{\tt To \: Find}} :$

• Area of the given square park = ?
• Total cost of planting grass in that square park = ?

$\large \underline{\underline{\tt Solution}} :$

As, we have side of square park is 120 m.

So, To find area of square park, we have a formula :

$\underline{\boxed{\bf{Area_{(square)} = (side)^{2}}}}$

$\sf : \implies Area_{(square \: park)} = (120\: m)^{2}$

$\sf : \implies Area_{(square \: park)} = 14400 m^{2}$

Hence, Area of given square park is 14400 m².

Now, we have to find cost of planting grass in given square park at rate of Rs. 12 per m².

$\sf : \implies Cost \: = Area \times Rate$

$\sf : \implies Cost \: of \: planting \: grass = Area_{(square \: park)} \times Rs. \: 12$

$\sf : \implies Cost \: of \: planting \: grass = 14400 \times Rs. \: 12$

$\sf : \implies Cost \: of \: planting \: grass = Rs. \: 172800$

Hence, cost of planting grass in given square park is Rs. 172800.
