Answer:
67.5
Step-by-step explanation:
Well area of a triange is 1/2bh so we can find the side closest to us by doing
1/2(3x4) which is 12
the other side would be 1/2 (3x5) which is 7.5
the bottom side would be 1/2(8x4) so 16
and 1/2 (3x8) so 12
1/2 (8x5) so 20
add those together to get 67.5
Hope this helped ya!

Step-by-step explanation:
Answer:
no Solution
Step-by-step explanation:
-12x-12y=4\\ 3x+3y=0
12x-12y=4
add 12y to both sides
12x-12y+12y=4+12y
divid both sides by -12
\frac{-12x}{-12}=\frac{4}{-12}+\frac{12y}{-12}
simplfy
x=-\frac{1+3y}{3}
\mathrm{Substitute\:}x=-\frac{1+3y}{3}
\begin{bmatrix}3\left(-\frac{1+3y}{3}\right)+3y=0\end{bmatrix}
\begin{bmatrix}-1=0\end{bmatrix}
