Answer:
First photo, I think they are all the same
Second, see below
Step-by-step explanation:
<u>Numbering is by the numbers next to the problem, not the order of the photos</u>
(2) Biggest area
[] Find alllll the areas and compare! Area is base x height divded by 2
[] A
2 x 4 / 2
8 / 2
4
[] B
2 x 4 / 2
8 / 2
4
[] C
2 x 4 / 2
8 / 2
4
[] D
2 x 4 / 2
8 / 2
4
Now, I think this is a trick question and they are all the same areas. I am not 100% sure, but if you do the math that is what you get :)
(1) Drawing heights
[] The height is from the middle of the base to the point across. For the one on the left you would find the of the base and draw a straight line into the corner across from it at the bottom right.
[] The one on the right would be the same, but it would go into the narrower corner on the top
(Hopefully this helps and is correct! Have a nice day :D)
I think its B but I’m not positive.
To work out the area of a compound shape you first have to split the shape and look for regular shapes i.e rectangles, squares, triangles.
area for a square is Length * Width also the same for a rectangle
area for a triangle = Base * Height / 2 (not the length)
Then you need to look which sides have already been given then work out how to find each missing side to work out the area.
It is best to learn this by looking for a youtube a tutorial as i can not show you what i mean by finding missing sides.
