Can anyone pls help me in this pls

Again a square means the side lengths are the same length. The hypotenuse is given to be 3 so we can easily solve for the side length using the pyth. theorem.

Let x = side length

2x² = 3²

2x² = 9

x² = 4.5

x = √4.5 = 2.1 m approx.

2.1 m approx.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
