A way that allows students to discover a strategy for determining the area of rectangles, squares, parallelograms, triangles, and trapezoids is described. Students use grid paper and scissors to determine the number of square units that cover a specified space. (KR)...
Finding the Area of Irregular FiguresLearning OutcomesCombine area of regular shapes to find the area of irregular shapes.So far, we have found area for rectangles, triangles, trapezoids, and circles. An irregular figure is a figure that is not a standard geometric shape. Its area can...

For a given convex n-gon P an O( n log 2 n) algorithm finds all local minima (with respect to area) among the triangles containing P. No areas are computed, for the algorithm is based on a simple geometric characterization of the local minima....
Normally, to find the surface area or volume of a rectangular prism, you need to work with a length, width, and height that are all different. But with a cube, you can take advantage of the fact that all sides are equal to easily calculate its geometry and find the area. ...
Answer to: Prove the Pythagorean theorem by finding the area of the figure in two ways: (A) As three triangles, (B) As a single trapezoid. By...
Finding the maximum area rectangle restricted to △ corresponds to the following problem (note that when 〈u,v〉=0, the area of ◊(x,u,v) is |u|⋅|v|):opt(△)=max|u|2⋅|v|2s.t.(x,u,v)∈△〈u,v〉=0 This is a constant-size problem. It has 6 variables and a ...
But there is another way: add the areas of the two triangles directly. left area + right area (5×8)/2 + (2×5)/2 = 20 + 5 = 25 cm2 But these two answers are different! What’s going on? The correct answer is 25 cm2and the wrong answer is the first method of 24.5 cm2...
