Answer:
B.) 4.18 square inches
Step-by-step explanation:
Find the area of the one right triangle and multiply it by two. The formula for the area of a triangle is:
[tex]A=\frac{1}{2} bh[/tex]
Insert the values. 1.1 is the base and 3.8 is the height:
[tex]A=\frac{1}{2} *1.1*3.8[/tex]
Simplify:
[tex]A=\frac{1*1.1*3.8}{2} \\\\A=\frac{4.18}{2} \\\\A=2.09[/tex]
Multiply the area of one triangle by two:
[tex]2.09*2=4.18\\\\A=4.18[/tex]
The total area of the shaded figures is [tex]4.18[/tex] [tex]in^2[/tex]
