WebMar 24, 2011 · It is not hard to guess that the area under a parabolic arch with base B and height H is 2/3*B*H (two thirds of the area of the circumscribed rectangle). Remarks. After students learn algebraic methods of computing integrals based on the Fundamental Theorem of Calculus, they will be able to derive the formula Y=(H-R 2)*X 2 and prove … WebArea = ½ × base × height. We know the base is c, and can work out the height: the height is b × sin A. So we get: Area = ½ × (c) × (b × sin A) Which can be simplified to: Area = 1 2 bc sin A. By changing the labels on the triangle we can also get: Area = ½ ab sin C.

WebLet me write that. x plus x plus x plus x, which is equal to 4x, which is going to be equal to 36. They gave us that in the problem. And to solve this, 4 times something is 36, you could solve that probably in your head. But we could divide both sides by 4, and you get x is equal to 9. So this is a 9 by 9 square. This width is 9.
