Nathan purchased a square sheet of kite paper to make a kite.
The area of the kite paper was 1600cm. While making the kite
he realised that the sheet of kite paper was 4cm short on one
side. What would be the dimensions of kite paper Nathan need
to properly make the kite?​

Answer 1

40 cm by 44 cm

Explanation:

A square sheet of paper has area 1600 cm^2.

area = s^2

1600 cm^2 = s^2

s = sqrt(1600 cm^2)

s = 40 cm

The side of the square was 40 cm, so the square measured 40 cm by 40 cm.

One side of 4 cm short, so the paper should have been 40 cm by 44 cm.
