Question

Silvio wants to find the perimeter of quadrilateral ABCD. He begins by computing the length of side AB using the distance formula. Finish Silvio’s work to find the length of side AB.

What is the perimeter of quadrilateral ABCD?

15 units
17 units
18 units
20 units

Answer 1

Answer: 20 units

Explanation:

Answer 2

AB = √(-4)² + (-3)²
AB = √ 16 + 9
AB = √ 25
AB = 5

AD = 4 ; DC = 4 ; BC = 7

Perimeter = 5 + 4 + 4 + 7 = 20 units
