600 and 60 I do not know what to do
V=lwh
198 = 3(x-1)(x-4)
(x-1)(x-4)=x^2-5x+4
3(x^2-5x+4)
= 3x^2-15x+12
3x^2-15x+12=198
Subtract 198 from both sides
= 3x^2-15x-186
use Quadratic formula <-- google if you forgot it
=10.761355820929152 and a different number which is negative, so reject it
Round it to 10.76
x=10.76
It would be the one where measurement 1m is the side of the triangle, measurement 0.75m is the bottom of the triangle, and measurement 2m is the long side of the rectangle
In this shape there will be 540 degrees
So 98+98+115+115+x = 540
X= 114
Hope this helps!
