Question

The side of a square is 5 cm. If its side is doubled, how many times is the area of the
new square bigger than the area of the old square?

Answer 1

Answer:

May be 2 times the area of the older square.

Step-by-step explanation:

side=5 cm.

area= S×S=5×5=10cm

if the side is doubled ,

side = 10cm

area=S×S=10×10= 20 cm.

Answer 2

■ ANSWER ■

• Area of a square =(side)²
• Area of a square =(side)²Side = 5 cm
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²If side is doubled then ,
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²If side is doubled then ,5*2= 10 cm
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²If side is doubled then ,5*2= 10 cmArea = (10)² = 100 cm²
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²If side is doubled then ,5*2= 10 cmArea = (10)² = 100 cm²100/25 = 4
• Area of a square =(side)²Side = 5 cmArea =( 5)² =25cm²If side is doubled then ,5*2= 10 cmArea = (10)² = 100 cm²100/25 = 4So the area increases by 4 times when the side is doubled.
