Question

I need help with this 5

Answer 1

The perimeter is the sum of each side of the square so we need to calculate them.

Use this formula:

`√((x_2-x_1)²+(y_2-y_1)²)`

Side A = 4.47

Side B = 4.47

Side C = 4.47

Side D = 4.47

since it is a square all sides are the same

then sum the four sides and that's your perimeter

= 17.888 which is 8 sqrt(5)
