There are numerous ways you can do this, but take a look at the attachment to see how I did it. I hope it answers your question! :)
Answer:
It's the first option
Step-by-step explanation:
The Midsegment Theorem states that the segment connecting the midpoints of two sides of a triangle (in this case AB and AC) is parallel to the third side (BC) and half as long.
The answer to the first question is 7
Second one is 200-400
First let us find area of triangles
area of 1st triangle is
1/2 x base x height
=> 1/2 x 1 x 5 = 5/2 cm^2
Now area of rectangle which is
Length x breadth
=> 12 x 5 = 60cm^2
Now area of 2nd triangle
=> 1/2 x 1.5 x 5
=> 15/4 cm^2
Total area = 5/2+60+15/4 = 265/4 cm^2
Or 66.25 cm^2
