Question

The side of a square field is 36 m. Find the cost of planting grass in it at the rate of #15 per sq. m.

​

Answer 1

Answer:

36*36 = 1296 m²

Step-by-step explanation:

first Total area of square field is

Area of square = (side)²

= (36)²

= 1296 m²

Now ,

Cost of planting the grass per m² is = 15

" ". ". ". in 1296 m² is = 15*1296

Total Cost = Rs 19440

$\orange{ \textsf{Side of playground = 36 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.15}}$

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

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

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

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

$\red{ \textsf{Area of playground = 36 x 36}}$

$\red{ \sf{Area \: of \: playground = 1296 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.15}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 1296 \: m² = 1296\times 15}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 1296 \: m² = Rs. \: 19440 }}$
