The area of a triangle is .5 x base x height
-13 and -5 hope this helps???
Sorry if it's wrong OnO''
Hello!
To find the surface area of a cube you do

where "a" is the length of one of the sides.
So

= 1350
the answer is 1350mm

Hope this helps!
Answer: D) 32
Step-by-step explanation:
The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:
A=bh
40=(5)(h)
h=8
If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to
where h is the height,
is one base, and
is the other base. Plug the necessary values into the formula:
A=


h=8
A=
A=32
The answer is D) 32.
