3. Find the lateral surface area of the figure below. 9 ft . 8 ft 10 ft 4ft​

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

When you answer this can you explain

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?
