Question

find the perimeter of rectangle qrst whose vertices are q(–2, 2), r(1, 0), s(0, –1), and t(–3, 1). a. 5.02 units b. 5.09 units c. 7.29 units d. 10.04 units

Answer 1

D: 10.04 units

Explanation:

Short to what is written above

Answer 2

Perimeter of a rectangle = 2(l + w)
Length =
`√((1+2)^2+(0-2)^2) = √(3^2+(-2)^2) = √(9+4) = √(13)=3.61`
Width =
`√((0-1)^2+(-1-0)^2) = √((-1)^2+(-1)^2) = √(1+1) = √(2)=1.41`

Perimeter = 2(3.61 + 1.41) = 2 x 5.02 = 10.04 units
