Hi there. I am having an issue figuring out which is the base and which is the length.

Paha777 [63]

We can split the given figure in 2 right triangles:

So, in order to get the area of each triangle, we need to find the base, denoted by x in both of them. Since both are right triangles, we can to apply Pythagoresn theorem. By applying this theorem to right hand side triangle, we have

$x^2+8^2=17^2$

so we have

$\begin{gathered} x^2+64=289 \\ then \\ x^2=289-64 \\ x^2=225 \end{gathered}$

Then, x is given by

$x=\sqrt{225}=15$

Then, the area of the left triangle is given by

$A_1=\frac{base\times height}{2}=\frac{15\times36}{2}=270in^2$

Similarly, the area of the second triangle is given by

$A_2=\frac{base\times height}{2}=\frac{15\times8}{2}=60in^2$

Then, the area of the entire figure is the sum of the area of the 2 triangles, that is,

$A=A_1+A_2=270+60=330in^2$

Therefore, the answer is: 330 square inches

Bas_tet [7]

The box she ship in has the volume of 1440 cubic inch. The cookie box is 60 cubic inch, so if you divided 1440 into 60, you would get 24. So. she can fit 24 cookie boxes into the box to be shipped.
