Decompose that into a rectangle and a right triangle by extending the 6 ft line down to the base. Find the area of both of those figures and add them.

Can you find the base and the height of that triangle? The area will be 1/2 * base * height.

See how the dimensions of the triangle come about? :)

dw:1359846112405:dwSo we want to find the area of these two objects separately. Then we'll add those area's together to get the `total area` of the figure.

Hmm did you forget the formula for area of a triangle maybe? :o

i multiplide 10 and 7 i got 70 then i multiplide 4 and 2 then i got 16 then i add them together which i got 86

The 70 looks good. \(4 \times 2 \ne 16\) , might wanna visit Mr Calculator for that one! :O And then remember, The area of a triangle we take `half` of the base times height.

Cool c: Just remember for a triangle,\[\large A=\frac{1}{2}b\cdot h\]

So we only want half of that 8 c:

dw:1359846808816:dwIf we had a square like this, the area would be 8, because 4 x 2 = 8.

dw:1359846855993:dwBut we have a triangle, which is half of that area.
