Mathematics
1 answer:
Delvig [45]3 years ago
3 0

Answer:

Step-by-step explanation:

Co-ordinates of F, G and H are:

F (-4, 5)

G (1, 10)

H (-9, 10)

You can find the lengths of sides by using the distance formula:

<em>length</em>(FG) = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}} = \sqrt{(1-(-4))^{2} + (10-5)^{2}} = 5\sqrt{2} units

Similarly,

<em>length</em>(GH) = 10 units

<em>length</em>(HF) = 5\sqrt{2} units

Hence, perimeter will be:

P = <em>length</em>(FG) + <em>length</em>(GH) + <em>length</em>(HF) = 10(\sqrt{2} + 1) units
