Understanding Area

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different...

Use the formula for the area of a rectangle for more than just rectangles! Scholars see that they can use common area formulas to find the area of irregular shapes. 

A critical skill in mathematics is using formulas to solve problems. Learners see the area formula for rectangles applied to three different types of problems. The video instructor demonstrates problems represented with a diagram,...

Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.

Sliding over a corner makes a rectangle. The resource demonstrates why the formula of the area of a parallelogram works. As part of a larger playlist on basic geometry, the video works examples dealing with parallelogram areas.

Multiply polynomials with Sal Khan! In this one-minute video, Sal describes what a monomial is, and how it can be used to express the area of a rectangle.

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This instructional activity can be...

In this online math worksheet, students calculate the area of a variety of rectangles given the measure of their vertices. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

Use Glencoe's randomly generated self-checking quiz to test your knowledge of finding the area of rectangles. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check...
