Answer:
Length = 27 metresWidth = 9 meters
Step-by-step explanation:
1. Remove parentheses
-3x^2 + x^4 + x + 2x^4 - 7 + 4x
2. Collect like terms
-3x^2 + (x^4 + 2x^4) + (x + 4x) - 7
3. Simplify
-3x^2 + 3x^4 + 5x - 7
v = pi(4)^2(16)
2nd choice from top
-4x^2? + 8x? + 11x^2 - 23x + 2
x = 110 degree
Hope this helps u !!
