Question

Each side of a square is 4cm. If each side of a square is increased by 25%, find the increase in area​

Answer 1

Answer:

think so

Step-by-step explanation:

if you increase both sides of a square by 25% (i.e. multiply by 1.25), then the new area is greater by 1.25 squared = 5/4 squared or 25/16.

The original square was 4cm squared = 16 cm^2, so the new, enlarged square has an area of 16 x 25 / 16 = 25 cm-squared.

Therefore the ratio is 25 : 16.
