Best ResponseYou've already chosen the best response.0Separate it into smaller wellknown shapes and find their areas. Then add up all the areas. By wellknown shapes I mean triangles and a rectangle.

Best ResponseYou've already chosen the best response.0Notice the height of the rectangle is from 3 to 8 on the yaxis. How far is it from 3 to 8?

Best ResponseYou've already chosen the best response.0The rectangle is 4 by 5, so the area fo the rectangle is A5 = 4 * 5 = 20

Best ResponseYou've already chosen the best response.0A3 = bh/2 = 4 * 2/2 = 4 A4 = bh/2 = 8 * 2/2 = 8

Best ResponseYou've already chosen the best response.0Now that we have all the small areas, we can find the total area. A = A1 + A2 + A3 + A4 + A5 = 2 + 4 +4 + 8 + 20

Best ResponseYou've already chosen the best response.0Just the rectangle in the middle is 20. The total area is the area of the rectangle plus the area of the 4 triangles. Just add up all the numbers above.

Best ResponseYou've already chosen the best response.0Wait. i just noticed a mistake I made. All the triangles are correct, but I didn't use the correct length for the rectangle. The rectangle is 6 by 4, so its area is A = LW = 6 * 4 = 24 The total area is A = 2 + 4 +4 + 8 + 24 A = 42
