Question

find the cost of painting
a square board of side 44cm at the rate of $7 per sq cm.

Answer 1

Answer:

Cost of painting a square board of side 44 cm at the rate of $7 per cm^2 is $13552.

Step-by-step explanation:

It is given that the length of side of the square is 44 cm.

============================

From the properties of square, we know : -

Area of square = side^2

===========================

Therefore,

⇒ Area of this sqaure = ( 44 cm )^2

⇒ Area of this square = 1936 cm^2

Thus,

⇒ Cost of painting = Rate of painting x area to be painted

= > Cost of painting = $7 / cm^2 x 1936 cm^2

= > Cost of painting = $7 x 1936

= > Cost of painting = $13552

Hence, cost of painting a square board of side 44 cm at the rate of $7 per cm^2 is $13552.
