Find the perimeter of squared garden if its area is 1369m2​
irina [24]

Answer:

the perimeter is of 148 m

Step-by-step explanation:

the perimeter is the sum of all sides so an square has all sides equal so we have

P = x+x+x+x = 4x

and the area is

A=x^2=1369m^2

so we find x

\sqrt{x^2}=\sqrt{1369}\\\\x=37

and now the perimeter

P=4x\\\\P=4(37)\\\\P=148
