Answer 1

Answer:

Area of square = l *l

Cost of painting per 1 Sq. Cm= rs 3

Cost of painting for 3600sq.cm= 3600* 3 = rs 10800

The cost of painting a square surface is Rs.10800

Step-by-step explanation:

Side of square = 60 cm

Area of square = $Side^2 = 60^2 = 3600 cm^2$

Cost of painting 1 sq.cm. = Rs.3

Cost of painting 3600 sq.cm. = Rs.3 \times 3600

Cost of painting 3600 sq.cm. = Rs.10800
