Question

Side of a square playground measures 170m. Find the cost of planting the grass on this at the rate of rs 80 per square metre.

Answer 1

area of square=side ×side

=170×170m^2

cost =₹2,312, 000

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

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

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

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

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

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

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

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

$\red{ \sf{Area \: of \: playground = 28900 \: {m}^{2} }}$

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

$\red{ \sf{Cost \: of \: planting \: grass \: 28900 \: m² = 28900 \times 80}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 28900 \: m² = Rs. \: 2312000 }}$

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

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