Question

Find the cost of painting square board of side 44 cm at the rate of Rs.7 per sq. cm.

Answer 1

AREA OF SQUARE = SIDE²
                                      =44²
                                      =1936 CM²
COST OF PAINTING = RS. 7 PER CM²
     FOR 1936 CM²= 7×1936
                                 =13552 RS.
COST OF PAINTING SQUARE BOARD = 13552 RS

Answer 2

The cost of painting the square board is Rs. 13552.

Side of square= 44cm

Area = side^2 = 44^2 = 1936 sq cm

The cost of painting square board per sq cm= Rs 7

So, the cost of painting the entire square board= Rate/sq cm* Area of square = 7*1936 = Rs. 13552.
