For example, the area of a 2" x 4" rectangle is 8 square inches while the area of a proportional 4" x 8" rectangle is 32 square inches. If appropriate for your class, point out that, to create a proportional rectangle, the scaling factor must be squared then multiplied by the area of the original rectangle, i.e., 22 x 8 square inches.
Space figures are figures whose points do not all lie in the same plane. In this unit, we'll study the polyhedron, the cylinder, the cone, and the sphere.
If practice in finding the area of an isosceles triangle is what you are looking for, then this is the place to be. Find the height of the triangle using the Pythagorean theorem. Plug in the integer, or decimal dimensions in the area of a triangle formula A = 1/2 * b * h and solve for the area. (16 Worksheets)
