Shadow:

Break the shape into multiple shapes then calculate each of their areas, then add them up. I see squares, rectangles, and triangles.

Shadow:

For squares and rectangles, calculate their area by multiplying the length by the height. For the triangle, multiple the base by the height, then by 1/2.

Shadow:

You will have to use the lengths of some of the other sides to determine the measurements of some shapes. It looks like a lot but give it some time and its a relatively simple problem.

bill533:

would it be 72 if my calculations are wrong

Shadow:

I haven’t worked it out since I am on mobile/in a car. But the total area would be greater than 72. Did you solve for a smaller shape?

bill533:

yes from my calculations it's 34

bill533:

or 23

Shadow:

what shape..

bill533:

square

Shadow:

What measurements does it have? and where is it?

bill533:

8

Shadow:

are you guessing because these numbers dont make sense

bill533:

i'm kind of in a rush right now shadow

Shadow:

I am on mobile so I can’t draw this out to help you. So if you don’t work with me, I am afraid I can’t help you.

Shadow:

Divide the shape into three rectangles and a triangle. This seems to be the easiest way.

bill533:

i think it would be 72

Shadow:

You should have a 4 by 9, 10 by 3, and a 15 by 5. Then the triangle is 4 by 4.

Shadow:

so 36 + 30 + 75 + 16(1/2)

Shadow:

see how the number is much greater than 72?

bill533:

149

bill533:

yes
