Question

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

Answer 1

Answer:

(7)^2=49

7+3=10

(10)^2=100

100-49=51

answer=51

Answer 2

Step-by-step explanation:

length of 0ne side=7 m

area, 7*7=49 m^2

as its side is increased by 3 therefore, new length o of one side=7+3=10 m

new area= 10*10=100 m^2

therefore increase in area = new area - initial area

=100-49

=51 m^2
