Question

Each side of a square is 7 m. If its each side be increased by 3 m, what will be the increase in its area.

Answer 1

Step 1: Calculating the area of the square with side 7m:
The area of the square is given by:
Area $=(side{)}^2$
$=7\times 7$
$=49m^2$

Step 2: Calculating the new area of a square with increased by 3 m:
New length after increasing each side by
$3m=7+3=10m$

The area of the square is given by:
$10\times 10$
$=100m^2$
