Answer:

Step-by-step explanation:

Find the area of the triangle sides

Area of a triangle: (1/2)bh

b-base

h-height

(1/2)x2x2=2

Multiply by the number of that type of side

2x2=4

Find the height of the rectangles

[tex]a^{2}+ b^{2} =c^{2}[/tex]

[tex]1^{2} +2^{2} =c^{2}[/tex]

1+4=[tex]c^{2}[/tex]

5=[tex]c^{2}[/tex]

[tex]\sqrt{5} =c[/tex]

c=2.2

Find the area of the rectangles

Area of a rectangle: base times height

2.2x3=6.6

Multiply by the number of rectangles

6.6x2=13.2

Find the area of the bottom rectangle

2x3=6    

Add the totals together

4+13.2+6=23.2

So the closest value would be 22
