Answer 1

Answer:

$31.5units^2$

Step-by-step explanation:

The shape shown above can be split into 2 triangles and 1 rectangle.

The formula for a triangle:

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

The formula for a rectangle:

$A=lw$

Area of triangle (both have the same lengths so you can just double the area):

$A=\frac{1}{2} (3)(3.5)\\A=5.25$

Area of rectangle:

$A=(7)(3)\\A=21$

Add the individual areas together to get the overall:

5.25 + 5.25 + 21 = 31.5
