Answer 1

Answer:

AE:$\sqrt{15300}$

DE:150

PABCDE: 720

Step-by-step explanation:

We can find AE by the pythagorean theorem, $a^{2}+b^{2}=c^{2}$

AE is the hypotenuse so AE=c, and the leg of the triangle would be 150-30=120

$50^{2}+120^{2}=c^{2}$

c^2=2500+14400

AE=130

We can use the pythagorean theorem again to find DE.

The base would equal 140-50=90 and the height would equal 120

$90^{2} +120^{2} =DE^{2}$

DE^2=22500

DE=150

The perimeter would be 150+140+150+130+150=720
