Question

A rectangle has vertices A(1, 3), B(1, 10), C(5, 10), and D(5, 3).

What is the perimeter of the rectangle?

Answer 1

The sides of the rectangle would be the width of 4 units and the length of 7 units
The equation of perimeter is P=2l+2w
If w=4 and l=7, the P=2(7)+2(4)
Therefore, P=14+8=22 units
