Answer 1

AE:
`√(15300)`

DE:150

PABCDE: 720

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
