Question

A side of a square was increased 4 times. What was the change in Area?

• A. 20 times
• B. 16 times
• C. 4 times
• D. Two times

Answer 1

The correct option is B

16 times

All sides in a square are equal.

Area of square $=\text{side}\times \text{side}$

Area is directly proportional to the square of the sides.

$\therefore$ If the Side is increased by 4 times, the area increases by $4\times 4=16\text{times}$.
