Question

The cost of planting grass square park of side 20m at the rate of ₹ 10 / sq m will be ​

Answer 1

Answer:

Rs. 4000

Step-by-step explanation:

Area of square field= (side)²= 20²= 400 m²

Required Cost= 400×10= Rs. 4000

$\red{ \textsf{The cost of planting grass on the playground is \orange{Rs.4000 .}}}$

$\huge \purple{ \underline{ \boxed{ \red{ \mathbb{EXPLANATION : }}}}}$

$\large\green{ \underline{ \underline{ \mathbb{GIVEN : }}}}$

$\orange{ \textsf{Side of playground = 20 m }}$

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

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

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

$\large\green{ \underline{ \underline{ \mathbb{SOLUTION : }}}}$

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

$\red{ \textsf{Area of playground = 20 x 20}}$

$\red{ \sf{Area \: of \: playground = 400 \: {m}^{2} }}$

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

$\red{ \sf{Cost \: of \: planting \: grass \: 400 \: m² = 400 \times 10}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 400 \: m² = Rs. \: 4000 }}$
