Al Capone Does My Shirts Discussion Guide. Area of Circle, Triangle, Square, Rectangle, Parallelogram, Trapezium, Ellipse and Sector. Area is the size of a surface!
Learn more about Area, or try the Area Calculator. Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height We know w = 5 and h = 3, so: Area = 5 × 3 = 15 Example: What is the area of this circle? Radius = r = 3 Example: What is the area of this triangle? Height = h = 12 Base = b = 20 Area = ½ × b × h = ½ × 20 × 12 = 120 A harder example: Example: Sam cuts grass at $0.10 per square meter How much does Sam earn cutting this area: Let's break the area into two parts: Part A is a square: Area of A = a2 = 20m × 20m = 400m2 Part B is a triangle.
Area of B = ½b × h = ½ × 20m × 14m = 140m2 So the total area is: Area = Area of A + Area of B = 400m2 + 140m2 = 540m2 Sam earns $0.10 per square meter Sam earns = $0.10 × 540m2 = $54. Surface Area Formulas. (pi = Surface Area Formulas In general, the surface area is the sum of all the areas of all the shapes that cover the surface of the object.
Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units Note: "ab" means "a" multiplied by "b". "a2" means "a squared", which is the same as "a" times "a". Be careful!! (a is the length of the side of each edge of the cube) In words, the surface area of a cube is the area of the six squares that cover it. (a, b, and c are the lengths of the 3 sides) In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. The area of the top and bottom (side lengths a and c) = a*c. (b is the shape of the ends) Surface Area = Lateral area + Area of two ends (Lateral area) = (perimeter of shape b) * L Surface Area = (perimeter of shape b) * L+ 2*(Area of shape b) Coffee problem.
