Question

If the side of a square be incresaed by 50 percent find the percent incress in area

Answer 1

area=s×s
=10×10
= 100
increase 50 percent
area=s×s
= 15×15
=225
answer - increase 125 percent

Answer 2

Answer:

Step-by-step explanation:

Let the original side of square is a

After an increase in the side by 50%,

New side = earlier side + 50% of earlier side

=a+50/100×a=a+a/2=3a/2

AREA OF THE SQUARE WHEN SIDE = a

Area of square=a²

AREA OF THE SQUARE WHEN SIDE = 3a/2

Area of square=(3a)²/2²=9a²/4

Area increase = New Area - Old Area

=9a²/4-3a/2=3a/4

Percentage increase = Area increase/old area × 100

                                 =(3a/4)/4a × 100            

                                  =18.74%
