Use Pythagorean Theorem (a² + b² = c²) to find the lengths of the sides. You can also use the distance formula.
6² + 14² = d²
36 + 196 = d²
232 = d²
15.23 ≅ d
2² + 5² = d²
4 + 25 = d²
29 = d²
5.39 ≅ d
Next, use the Perimeter formula:
P = 2L + 2w
= 2(15.23) + 2(5.39)
= 30.46 + 10.78
= 41.24
For #6, Use the Area formula:
A = L x w
= 5.39 x 41.24
= 222.28
