Perimeter

This 11-question quiz is about finding the perimeter, the total distance around a shape.

It mixes formula recall with calculation, asking things like Which is the formula for finding the perimeter of a triangle? and Find the perimeter of a square having side length of 4 cm.

The shortcut worth holding onto is that for any regular shape, where all the sides are equal, you can just multiply one side length by the number of sides.

It also stretches to less common shapes like the octagon, so it is good practice beyond the usual square and rectangle.

Recommended level: beginner to intermediate.
