Simplify this please (35)(447)

Ineed in figuring out this problem.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%

Given: prst square pmkd is a square pr = a, pd = a find the area of pmct.
