In this geometry exercise, children calculate the perimeter of various trapezoids by adding up the lengths of their sides.

Students explore the relationships between the side lengths and angle measures of triangles in this seventh-grade geometry worksheet!

Students will find approximate areas for surfaces in their own environment by using pictures, numbers, and words to answer the geometric word problems.

This math worksheet calls on students to examine the objects in their environment, measure them, and calculate the surface area in centimeters or inches.
