Answer:
LA = 120 sq cm
SA = 132 sq. cm.
Step-by-step explanation:
LA = ph where p = perimeter of the base and h = the height of prism.
Your base is a triangle. The third side = =
Now, the perimeter of the triangle is 3 + 4 + 5 = 12
So, LA = 12(10) = 120 sq cm
The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6
SA = 2B + LA where B is the area of the base
SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.

Answer:
<em>The endpoint coordinates for the mid-segment are: and
</em>
Step-by-step explanation:
According to the given diagram, the coordinates of the vertices of are:
and
Now, the endpoints of the mid-segment of which is parallel to
will be the mid-points of sides
and
.
<u>Formula for the coordinate of mid-point</u> : , where
and
are two endpoints.
So, the mid-point of will be:
and the mid-point of will be:
Thus, the endpoint coordinates for the mid-segment of that is parallel to
are
and
