Question

what is the area of a square Park whose side is 150 m?Find the total cost of planting grass in it at rupees 10 per square meter

Answer 1

Given :

Side of square park = 150 m

To Find :

what is the area of a square Park whose side is 150 m?Find the total cost of planting grass in it at rupees 10 per square meter

Solution:

Side of square park = 150 m

Area of square park =$Side^2 = 150^2 =22500$

Cost of planting grass in 1 sq.m.= rs.10

Cost of planting grass in 22500 sq.m.=$22500 \times 10=225000$

Hence The cost of planting grass is Rs.225000 and the area of a square Park is 22500 sq.m.

$\orange{ \textsf{Side of playground = 150 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.10}}$

$\large\green{ \underline{ \underline{ \mathbb{FORMULA \: USED : }}}}$

$\orange{ \textsf{Area of Square = Side x Side}}$

$\red{ \textsf{Area of playground = Side x Side }}$

$\red{ \textsf{Area of playground = 150 x 150}}$

$\red{ \sf{Area \: of \: playground = 22500 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.10}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 22500 \: m² = 22500 \times 10}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 22500 \: m² = Rs. \: 225000 }}$
