Answer:
Perimeter: 15 feet, Area: 15 square feet.
Step-by-step explanation:
You need this fast, so I'll spare you of much description. Add the side lengths for perimeter, and multiply the sides that aren't the hypotenuse (the legs) for the area.
-7/10 (fraction)
-0.7 (decimal)
345.95−100
=245.95
22.92×12
=275.04
((275.04−245.95)÷245.95)
×100
=11.8%
