Question

If each side of a square is increased by 10 it's area will be increased by

Answer 1

Heya !

Here's your answer.. ⬇
__________________________

Let the side of square = s
Area of square = s²

Given that side of square is increased by 10%.

side by increasing 10% = ( 1 + 1/100 )
new side of square = 1.1s

Area of new square = ( 1.1s )²
= 1.21s²

Total increase area = New square area - area of square
= 1.21s² - s²
= 0.21s²

Now, percentage of increased area
=( 0.21s²/ s² ) × 100
= 0.21/100
= 21%

Hence, area of square will increase by 21% .

Answer 2

Answer:

Here's your answer.. ⬇

Step-by-step explanation:

Let the side of square = s

Area of square = s²

Given that side of square is increased by 10%.

side by increasing 10% = ( 1 + 1/100 )

new side of square = 1.1s

Area of new square = ( 1.1s )²

= 1.21s²

Total increase area = New square area - area of square

= 1.21s² - s²

= 0.21s²

Now, percentage of increased area

=( 0.21s²/ s² ) × 100

= 0.21/100

= 21%

Hence, area of square will increase by 21% .
