Length, Perimeter and Area

Make a coordinated effort to draw an altitude. Using an obtuse triangle plotted on a coordinate plane, scholars determine the perimeter and area of the triangle. after determining the lengths of the sides using the coordinates, learners...

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 area...

Alternate between area and perimeter with this instructional activity, practicing both concepts with different shapes. Problems include examples with parallelograms, octagons, squares, rectangles, and trapezoids. The formulas are not...

There are many different polygons, so give your learners a worksheet that practices area and perimeter on the various shapes. This full-page worksheet includes problems with hexagons, trapezoids, squares, parallelograms, and rectangles....

Test your mathematicians' skills with this full page of area and perimeter problems. Find the area and perimeter of different shapes including squares, parallelograms, trapezoids, and octagons. The formulas are not provided, so this...

In this ratio, perimeter and area worksheet, students find the scale factor of similar rectangles. They identify the ratios of their widths and lengths. Students justify their answers through written explanations. This two-page worksheet...

When algebra and geometry get together, good things happen! Given a system of inequalities that create a quadrilateral, learners graph and find vertices. They then use the vertices and Green's Theorem to find the area and perimeter of...

Teach your class how calculate the perimeter and area of a square by creating graphs. They graph different polynomial functions using the Ti calculator.

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Learners calculate area, perimeter and length of rectangles. In this geometry lesson plan, students create different formulas for the problem they are being asked to solve. They use the navigator to move the shape around and make...
