Step-by-step explanation:

x^2=2^2+13^(1/2)^2

x^2=4+13

x^2=17

x=4.1 (to nearest tenth)

12

Step-by-step explanation:

What I did was I divide it so there would be two triangles and a square. One triangle going across the 2 on the y-axis and another triangle going down the -2 on the x-axis and the shape left over is the square

The top triangle:

A = bh

A = 4 x 2

A = 8

A = 4

The square:

A = L x H

A = 3 x 2

A = 6

Left side triangle:

A = bh

A = 2 x 2

A = 4

A= 2

2 + 6 + 4 = 12
