What is the missing length?

Question image

Understand the Problem

The question is asking for the missing length 's' of a triangle given its base length (10.3 mm) and the area (45.835 mm²). To find 's', we can use the formula for the area of a triangle: area = 0.5 * base * height.

Answer

The missing length \( s \) is approximately \( 8.9 \) mm.
Answer for screen readers

The missing length ( s ) is approximately ( 8.9 ) mm.

Steps to Solve

  1. Set up the area formula for a triangle

We know the formula for the area of a triangle is:

$$ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} $$

Here, the area is given as 45.835 mm², and the base is 10.3 mm.

  1. Substitute the known values into the formula

Plugging in the values we have:

$$ 45.835 = \frac{1}{2} \times 10.3 \times s $$

  1. Isolate 's'

To find 's', first multiply both sides by 2:

$$ 2 \times 45.835 = 10.3 \times s $$

This simplifies to:

$$ 91.67 = 10.3 \times s $$

Next, divide both sides by 10.3 to isolate 's':

$$ s = \frac{91.67}{10.3} $$

  1. Calculate the value of 's'

Now we perform the division:

$$ s \approx 8.9 \text{ mm} $$

The missing length ( s ) is approximately ( 8.9 ) mm.

More Information

This calculation shows how to use the area formula of a triangle to find the height given the base and the area. The height is essential for understanding the triangle's dimensions.

Tips

  • Forgetting to multiply the area by 2 when rearranging the formula can lead to an incorrect calculation.
  • Mixing up the base and height in the area formula can cause confusion.
