Question

The length and breadth of a rectangular Park are 75 metre and 40 metre respectively find the area of the park and the cost of planting grass in it at
20 per metre square

Answer 1

Answer:

Step-by-step explanation:

Area of rectangle =length ×breadth

=75×40

=3000 meter square

Cost of planting grass (per m^2)

=cost × area

=3000×20

=60000 Rs

$\red{ \textsf{The cost of planting grass on the playground is \orange{Rs.60000 .}}}$

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

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

$\orange{ \textsf{Length of playground = 75 m }}$

$\orange{ \textsf{Breadth of playground = 40 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.20}}$

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

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

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

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

$\red{ \textsf{Area of playground = 75 x 40}}$

$\red{ \sf{Area \: of \: playground = 3000 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.20}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 3000 \: m² = 3000 \times 20}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 3000 \: m² = Rs. \: 60000 }}$

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

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

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