let length of one piece = x
length of other piece = 236-x
one piece is three times the length of the other
x=3(236-x)
x=708-3x
4x=708
x=177
so first piece is 177 inches long and second piece is (236-177)= 59 inches long
Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5
hope this helps :)
The expression would be (X-6)/7
