Finding Area with Fractional Side Lengths

Front

What is area?

Back

Area is the amount of space inside a shape, measured in square units.

Front

How do you find the area of a rectangle?

Back

Multiply the length by the width (Area = Length × Width).

Front

What is a fractional side length?

Back

A fractional side length is a measurement of a side of a shape that includes a fraction, such as 3/4 or 2/3.

Front

What is the area of a rectangle with a length of 3/4 units and a width of 5 units?

Back

Area = 3/4 × 5 = 15/4 square units.

Front

If a rectangle has a length of 2/3 units and a width of 4 units, what is its area?

Back

Area = 2/3 × 4 = 8/3 square units.

Front

What does it mean to color a part of a shape?

Back

It means to shade or fill in a specific area of the shape to represent a portion of it.

Front

How do you express the area of a shaded region in a diagram?

Back

You can express it as a multiplication of the fractional side lengths, such as 2/4 × 9.

Front

What is the area of a garden that is 3 3/4 units long and 3 units wide?

Back

Area = 3 3/4 × 3 = 11 1/4 square units.

Front

What is the formula for finding the area of a shape with fractional dimensions?

Back

Multiply the fractional lengths together (Area = Fractional Length × Fractional Width).

Front

How can you simplify the expression 3 divided by 15/4?

Back

To simplify, multiply by the reciprocal: 3 × 4/15 = 12/15 = 4/5.
