Question

each side of a square is 7m if its each side is increased by 3m. Then what will be the increase in area​

Answer 1

Answer:

51

Step-by-step explanation:

Area= side×side

7+3= 10

So,

10×10=100.

7×7=49

increase in Area- 51

Answer 2

Answer:

Answer. so, area of square after increased side is 100m^2.

Step-by-step explanation:

Given

The side of square =7 m

Hence, the area of square can be calculated as follows:

Area =(side)

2

Area =(7 m)

2

7 m×7 m

We get,

=49 m

2

Given each side is increased by 3 m,

So the new length of side will be =3 m+7 m

=10 m

Hence, the area od square can be calculated as follows:

Area =(side)

2

Area =(10 m)

2

=10 m×10 m

We get,

=100 m

2

Increases in area can be calculated as below:

Increase in area =100 m

2

−49 m

2

=51 m

2

Therefore, the increase in area of square =51 m
