Best ResponseYou've already chosen the best response.0Decompose 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.

Best ResponseYou've already chosen the best response.0Can you find the base and the height of that triangle? The area will be 1/2 * base * height.

Best ResponseYou've already chosen the best response.1See how the dimensions of the triangle come about? :)

Best ResponseYou've already chosen the best response.1dw: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.

Best ResponseYou've already chosen the best response.0i 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

Best ResponseYou've already chosen the best response.1The 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.

Best ResponseYou've already chosen the best response.1Cool c: Just remember for a triangle,\[\large A=\frac{1}{2}b\cdot h\]

Best ResponseYou've already chosen the best response.1So we only want half of that 8 c:

Best ResponseYou've already chosen the best response.1dw:1359846808816:dwIf we had a square like this, the area would be 8, because 4 x 2 = 8.

Best ResponseYou've already chosen the best response.1dw:1359846855993:dwBut we have a triangle, which is half of that area.
