Drained Reclamation or Deep Cement Mixing? Which one do you think is the better method of land reclamation and why? (Just looking for opinions btw!)

AE:

DE:150

PABCDE: 720

Step-by-step explanation:

We can find AE by the pythagorean theorem,

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

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

DE^2=22500

DE=150

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

Let me know if somethings wrong

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
