If the width of a rectangle is 2 cm, what is its length? Remember, you can multiply the length by the width to find the area of a rectangle.

Question

Area of a
rectangle (cm
2
) Length of a
rectangle (cm)
16

Answer 1

To find the length of the rectangle when the area is given, you can use the formula for the area of a rectangle:

\[ \text{Area} = \text{Length} \times \text{Width} \]

In this case, you want to find the length when the area is 16 cm² and the width is 2 cm.

Plugging in the values:

\[ 16 = \text{Length} \times 2 \]

To find the length, divide both sides by 2:

\[ \text{Length} = \frac{16}{2} = 8 \text{ cm} \]

So, the length of the rectangle is 8 cm.
