Question

A playground measures 275 m by 180m find the cost of planting grass on it at the rate of rs 190 per hectares

Answer 1

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

$\red{ \textsf{The cost of planting grass on the playground is \orange{Rs.940.5 .}}}$

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

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

$\orange{ \textsf{Length of playground = 275 m }}$

$\orange{ \textsf{Breadth of playground = 180 m }}$

$\orange{ \textsf{Cost of planting grass per hectare = Rs.190}}$

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

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

$\orange{ \sf{1 \: hectare = 10000 \: {m}^{2} }}$

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

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

$\red{ \textsf{Area of playground = 275 x 180}}$

$\red{ \sf{Area \: of \: playground = 49500 \: {m}^{2} }}$

$\red{ \sf{Area \: of \: playground = 4.95 \: hectare }}$

$\red{ \textsf{Cost of planting grass per hectare = Rs.190}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 4.95 \: hectare = 4.95 \times 190}}$

$\red{ \sf{Cost \: of \: planting \: grass \:4.95 \: hectare = Rs. \: 940.5 }}$

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

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

$\orange{ \mathbb{HECTARE :}}$

The hectare is a non-SI metric unit of area equal to 10,000 m² .
