Find the perimeter of the polygon with the given vertices.?
1. K(−1, 1), L(4, 1), M(2, −2), N(−3, −2)
2.Q(−4, −1), R(1, 4), S(4, 1), T(−1, −4)

Use the distance formula from vertex to vertex then add the 4 sides together to find the perimeter of each quadrilateral.

1) Use the distance formula: √[(x2-x1)^2 + (y2-y1)^2]
- the distance from K-L = 5
- the distance from L-M = √5
- the distance from M-N = 5
- the distance from N-K = √5
Perimeter = 5+ √5 + 5 + √5 = 10+2√5
2) Use the distance formula: √[(x2-x1)^2 + (y2-y1)^2]
- the distance from Q-R = √50
- the distance from R-S = √18
- the distance from S-T = √50
- the distance from T-Q = √18
Perimeter = √50+ √18 + √50 + √18 = 2√50 + 2√18
