Grade 6 Polygons, Area and Volume

What is the difference between Regular Polygons and Irregular Polygons?

• Regular polygons have all equal side lengths and irregular polygons do not have equal side lengths.

• Regular polygons have all equal side lengths and angle measurements and irregular polygons do not have equal side lengths and angle measurements.

• Regular polygons have all equal angle measurements and irregular polygons do not have equal angle measurements.

Polygons are closed, straight edged shapes where the lines meet at a vertex.

• False

• True

• This is a concave polygon.

• This is a convex polygon.

• This is a non-polygon.

• This is a concave polygon.

• This is a convex polygon.

• This is a non-polygon.

The area of grandpa's garden is 45 sq. meters. The length is 9 meters. What is the width?

• 7 meters

• 4 meters

• 5 meters

• 6 meters

The formula for area is:

• A = l + w

• A = lw

• A = l + l + w + w

• A = lwh

The formula for Area is A= lw.

It also be written as Base = lw

• True

• False

The formula for volume is:

• V = l + w + h

• V = lw

• V = lwh

• V = (l + w + h)2

The formula for Volume is V = lwh (V=length x width x height)

It also be written or thought of as V = bh (V= base x height)

• False

• True
