PLZ HELP FIND THE PERIMETER
seropon [69]

Answer:

254 ft

Step-by-step explanation:

first find the legs of the triangle.

you already know 65, and you would get another leg by 83-50, which equals 33.

Next use pythagorean theorem to find the other leg

a^2+b^2=c^2

rearrange so you find a leg

a^2=c^2-b^2

a^2=65^2-33^2

a^2=4225-1089

a^2=3136

a=56

Now you know that the missing leg is 56. Since that leg is the same as the short side of the rectangle, you 83+50+65+56=254
