<span>1. Quadrilateral QRST has vertices Q(a, b), R(0, 0), S(c, 0), and T (a + c, b). ... 1. The coordinates of quadrilateral ABCD are A(-1, -5), B(8, 2), C(11, 13), and D(2, 6). ... vertices of parallelogram ABCD are A(-3, 2), B(-2, -1), C(4, 1), and D(3, 4).</span>
The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.
