Answer:
Base = 16, height 64
Step-by-step explanation:
It's a triangle so u have to multiply it with 1/2 or divide by 2, x will equal both height and base:
(1/2)4x^2 = 512
Multiply 2 to both sides
4x^2 = 1024
divide both sides by 4
x^2 = 256
=
x = 16, base is 16 and height is 16(4) = 64
Alright this took me some time but I got it now, u might think why 16 and 64? 16 times 64 is not 512, but the equation for a triangles area is or b·h·1/2 , so if u plug the numbers into the equation it will equal 512:
16 · 64 · 1/2= 1024 · 1/2 = 512
