Answer

Perimeter: $68$ $inches$ Area: $185in^{2}$

Work Step by Step

For the perimeter: First, find the missing side lengths. To find the first one, subtract $23$ $-$ $6$. When you subtract those two, you will get one missing side: $17$. To find the other missing side, subtract $11$ $-$ $7$ $=$ $4$. So $4$ is the other missing side length. Then, to find the perimeter, add all the sides: $11$ $+$ $6$ $+$ $4$ $+$ $17$ $+$ $7$ $+$ $23$ $+$ $=$ $68$. Add the label, and your answer is $68$ $inches$ For the area: Cut the shape into 2 rectangles. Then use the formula $Area of a rectangle$ $=$ $length$ $\times$ $width$ to find the area of the two shapes. Then, add the 2 areas together to find the total area. Add the label of $in^{2}$ and you're done! The picture below shows the work done.
