5+4+2 + 15,25 = 26,25 unit squared

That would be incorrect... first off find the area of the larger triangle... so we would input it into the area of a triangle formula...\[A=\frac{ (2+2+5)\times3.5 }{ 2 }\] we add these numbers becuase they make up the entire length of the larger triangle..

OpenStudy (shaleiah):

I got 15.75

563blackghost (563blackghost):

Correct ^^ we would now find the area of triangle on the bottom left so we input this in are of a triangle formula...\[A=\frac{ 2\times2 }{ 2 }\]

OpenStudy (shaleiah):

2

563blackghost (563blackghost):

Correct ^^ Now we find the area of the next triangle at the bottom right corner...so \[A=\frac{ 5\times2 }{ 2 }\]

OpenStudy (shaleiah):

5

563blackghost (563blackghost):

Yup ^^ Now we find the area of the square so \[2\times2\]

OpenStudy (shaleiah):

4

563blackghost (563blackghost):

Correct once again ^^ Now we add up all the areas together to get the total area of the irregular shape...so\[15.75+2+5+4=total|area\]

OpenStudy (shaleiah):

26.75

563blackghost (563blackghost):

Correct ^^
