Answer:
I saw this question wasn't answered by anyone yet so I can help you with this one!
A is 8
B is 4
C is 3
D is 5
Area: 100
Now to find area with these its the same except for the triangles here in this photo I showed the area for each figure BY ITSELF so the thing with the triangles the formula is to do base × height thennn ÷ by 2 So i did 4 × 3 = 12 then divide by 2 and got 6 for both of those triangles as you see in the photo! Then I just did base × height for the rectangles! I did 8 × 4 = 32 and since it had a matching rectangle there was another 32 as displayed in the photo then the middle triangle I simply just did 8 × 3 cause thats the base and height and I got 24 now we just have to add these up! 6 + 6 + 32 + 32 + 24 = 100 so 100 is our area! Hope that makes sense and an easy trick for those triangles to remember to divide by 2 is a triangle is half of a rectangle/square like I displayed in another photo Hope that helps!
