Find the area of the shape shown below.

42.5

Step-by-step explanation:

Is this from khan? Meh, anyways, we need to find the area of the missing sides first.

The formula for area of a triangle is:

1/2(b×h)

So we multiply two and two and you get four. 2×2=4

Then you divide and that would be two. 4÷2=2

For the next one, you do the same.

You multiply five and two, which gives you ten. 5×2=10

Then you divide by two, which gives you five. 10÷2=5

Then you add the missing area lengths together to get a total of seven.

Then you would find the entire area. By that, I mean the whole thing.

I'm not sure if you noticed but the height of the missing triangle on the left is two.

2+3.5=5.5.

So that means that we have found out the entire height.

5.5×9=49.5

But that's not the answer. That's because the shape most certainly not a whole shape. It has some missing parts, if you see what I mean.

So that means that you have to subtract the area missing from the total area. That would be

49.5  -  7  =   42.5

total  missing  actual

area  area        area
