Question

Find the perimeter and area of the polygon defined by the points (7, 12), (1.0,6), (7.0), (2.0), and (-2, 12),

Answer 1

perimeter: 40.79

Area: 84

Explanation:

It's made up with 2 trapezoids

perimeter: (√3² + 6²) + (√1² + 6²) + 7 + 6 + 6 + 9 = 40.79

area: ((9 + 6) x 6) / 2 + ((6 + 7) x 6) / 2) = 45 + 39 = 84
