Answer:
P = 76 feet, A =338 square feet
Step-by-step explanation:
You got perimeter right, so I assume you don't need explaining.
The area for the rectangle is 270 square feet since 18 x 15 = 270. The area of the triangle is 68 since 17 x 8 is 136, and dividing by 2 gives 68.
Now add 270 and 68, which gives 338 square feet.
