Question

Find the perimeter of the image below:

Figure QRSTU is shown. Q is at 2, 0. R is at 4, 5. S is at 8, 7. T is at 6, 4. U is at 10, 3.

Answer 1

We can just use the distance formula a bunch

Distance from Q to R = \(\large \sqrt{(4 - 2)^2 + (5 - 0)^2}\)
Distance from R to S = \(\large \sqrt{(8 - 4)^2 + (7 - 5)^2}\)
Distance from S to T = \(\large \sqrt{(6 - 8)^2 + (4 - 7)^2}\)
Distance from T to U = \(\large \sqrt{(10 - 6)^2 + (3 - 4)^2}\)
Distance from U to Q = \(\large \sqrt{(2 - 10)^2 + (0 - 3)^2}\)

And then add up all the results :)

Answer 2

25.8 units

26.1units

27.5 units
