Answer 1

Answer:

$7\ mm^{2}$

Step-by-step explanation:

we know that

The area of the resulting two-dimensional cross-section is the area of a rectangle

see the attached figure to better understand the problem

The area of a rectangle is equal to

$A=bh$

we have

$b=3.5\ mm$

$h=2\ mm$

substitute

$A=3.5*2=7\ mm^{2}$

Answer 2

The area would be 90 since a right angle is 90 degrees also anything tha is across from the parrel side will be the same exact thing
