Question

The diagonal of a square is 4/2 cm. Then find the following:
a. Length of each side
b. Perimeter of the square
​

Answer 1

Answer:

Step-by-step explanation:

This is the relation between area and diagonal

$A=(1/2)d^2$

by putting values

A=2 cm

and also A=l^2

so l=$\sqrt{A}$

$\sqrt{2}$

perimeter is the sum of all sides l+l+l+l (square has 4 sides)

then $4\sqrt{2}$

is the perimeter
