Answer 1

I think this is the answer

Answer 2

$\red{ \textsf{The cost of planting grass on the playground is \orange{Rs.4080000 .}}}$

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

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

$\orange{ \textsf{Length of playground = 300 m }}$

$\orange{ \textsf{Breadth of playground = 170 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.80}}$

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

$\orange{ \textsf{Area of rectangle = Length x Breadth}}$

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

$\red{ \textsf{Area of playground = Length x Breadth}}$

$\red{ \textsf{Area of playground = 300 x 170}}$

$\red{ \sf{Area \: of \: playground = 51000 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.80}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 51000 \: m² = 51000 \times 80}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 51000 \: m² = Rs. \: 4080000 }}$

$\large \green{ \underline{ \underline{ \mathbb{KNOW \: MORE : }}}}$

$\orange{\mathbb{AREA : }}$

The area is the measurement of space enclosed by a closed geometric figure .
