Suppose you must find an unknown side using the hypotenuse (13 cm) and a known side (12 cm). To find the arc length with a sector area, multiply the sector area by 2. Then, divide the product by the radius squared ((SA*2)/r^2). Your answer gives you the central angle in radians. You now have the central angle in radians, so simply multiply the central angle by the radius to find the arc length.

So our original triangle is just going to have half the area. So this area right over here is going to be one half the area of the parallelogram, one half base, lemme do those same colors.
