The area of a triangle is found using the formula A=.5(base)(height). You can plug in your known values to solve for the base of the triangle. (It should look something like 600=.5(40)(x), where you can combine to get 600=20x, divide by 20, and get that x =30.). Next, to find the diagonal length of the triangle, you use the Pythagorean theorem, which is $a^{2} +b^{2} =c^{2}$ . You plug in 40 for a, and 30 for b, and solve to get that c is 50. You now have all of your missing side lengths. You add them all together (40+70+70+30+50) to get 260.
