Question

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(5, 1), B(7,1) C(7, 6) and D(5, 6) What is the perimeter of rectangle ABCD units

Answer 1

Answer: perimeter is 14 units

Step-by-step explanation:

You could use the distance formula to find the lengths of segments AB, BC, CD, and DA; or you could graph rectangle ABCD and note that you can count out the spaces to find the lengths of each side. Option 2 is easier in my opinion. Check out the diagram below. The horizontal portion is 2 units and the vertical part is 5

perimeter = 2*(length+width)

perimeter = 2*(5+2)

perimeter = 2*7

perimeter = 14
