Question

Luella drew the triangle shown on a coordinate grid. To find the triangle’s area, she multiplies 1/2 by 2 and then multiplies the result by another number. What is the number Luella can use to complete the calculation? (1 point) Luella can multiply 1/2 by 2 by to find the triangle’s area.

Answer 1

To calculate the area of a triangle using the formula \( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \), we observe that Luella has already multiplied \( \frac{1}{2} \) by \( 2 \). This suggests that the base of the triangle is \( 2 \).

To complete the calculation, Luella needs to multiply by the height of the triangle. Therefore, to complete her area calculation, the number she can use is the height of the triangle.

If you have the specific height of the triangle, you can substitute that number for the complete calculation. Otherwise, you can simply state that the missing number is the height of the triangle.
