Question

I NEED HELP CAN YALL PLEASE HELP ME WITH THIS?

Answer 1

P=4+√5+√13 the answer is C

Explanation:

to find the perimeter , need to find the length(distance of the sides)

D=√(x2-x1)²+(y2-y1)²

D between BE and BD and ED

d of BE :

B(1,2) E(5,2)

D of BE = √(5-1)²+(2-2)²=√4²=4

BE=4

D of BD : (1,2) , (2,4)

D=√(2-1)²+(4-2)² = √1²+2² = √5

BD=√5

ED : (5,2) , (2,4)

d=√(2-5)²+(4-2)²=√-3²+2² =√13

ED=√13

the perimeter= BE+BD+ED

P=4+√5+√13

Answer 2

I believe the answer would be C, but I'm not sure.
