Question

a. The perimeter of a square is 3.5m, find its area.​

Answer 1

Answer:

0.72

Step-by-step explanation:

4a=3.5

a=3.5/4

area of square=a*a

a^2=3.4/4*3.4/4 =0.72

Answer 2

Answer:area=0.765625

Step-by-step explanation:Given perimeter of square is 3.5cm

And are is to calculate

Now we know that the perimeter of square is 4*side. Let side be a

Then perimeter =4a=3.5

Then a =3.5/4=0.875

Formula of area =side *side=a^2=(0.875)^2=0.765625

Area=0.77approx
