What is the length of each side of a square that has an area of 9 units²?

Consider a square, whose diagonal measured d units
Area of Square =d&1\2.the area of this square can be calculated using the formula Area=d2\2.
let us consider a square whose sides measures a units.
the side being a here, we have Area=a^2
measure diagonal be d units.Diagonal divides the square into 2 right triangles.
And so 9^2 is 81 or it maybe 18 since it's using length so add  and then ,multiply since it's also using area so then, 9^2 and 9^2 and 9^2 you'll find your answer by  ADDING 9 UNITS AND THEN MULTPLY YOUR ANSWER YOU GOT FROM ADDING 9 UNITS WITH WHAT YOU GET WITH YOUR EXPONENT.

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
