Front

What is the formula to find the perimeter of a rectangle?

Back

L + W + L + W or 2L + 2W

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its area?

Back

15 square units (5 x 3)

Front

If a rectangle has a length of 4 units and a width of 2 units, what is its perimeter?

Back

12 units (4 + 2 + 4 + 2) or 2(4 + 2) = 12

Front

True or False: The area of a rectangle can be the same as its perimeter.

Back

True, but it depends on the dimensions.

Front

What does it mean if two figures have the same area but different perimeters?

Back

They cover the same amount of space but have different boundary lengths.

Front

If a rectangle has an area of 24 square units, what could be its possible dimensions?

Back

Possible dimensions include 6 x 4, 8 x 3, 12 x 2, etc.

Front

What is the relationship between area and perimeter in rectangles?

Back

Area measures the space inside, while perimeter measures the distance around.

Front

If Figure A has an area of 20 square units, can Figure B have the same area but a different shape?

Back

Yes, different shapes can have the same area.

Front

What is the maximum area of a rectangle with a perimeter of 12 units?

Back
