Question

The side of a square field is 82 m. Find the cost of laying grass in it at 50 paisa per square metre.​

Answer 1

Answer:

Side is 82m

Area = 82*82 = 6724 sq.m.

Cost is 50 paise per sq.m.

so total cost = 50*6724 = 336200 paise

1 paise = 0.01 Rs.

336200 paise = 336200*0.01

= 3362 Rs.

Cost is 50 paise per sq. m. 1 paise = 0.01 Rs. = 3362 Rs.

$\orange{ \textsf{Side of playground = 82 m }}$

$\orange{ \textsf{Cost of planting grass per m² = Rs.0.5}}$

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

$\red{ \textsf{Area of playground = 82 x 82}}$

$\red{ \sf{Area \: of \: playground = 6724 \: {m}^{2} }}$

$\red{ \textsf{Cost of planting grass per m² = Rs.0.5}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 6724 \: m² = 6724 \times 0.5}}$

$\red{ \sf{Cost \: of \: planting \: grass \: 6724 \: m² = Rs. \: 3362 }}$
