Answer 1

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:

$A=\frac{1}{2} bh$

Insert the values. 1.1 is the base and 3.8 is the height:

$A=\frac{1}{2} *1.1*3.8$

Simplify:

$A=\frac{1*1.1*3.8}{2} \\\\A=\frac{4.18}{2} \\\\A=2.09$

Multiply the area of one triangle by two:

$2.09*2=4.18\\\\A=4.18$

The total area of the shaded figures is $4.18$ $in^2$
