Question

what is the missing length? area = 312 m² y = meters

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $A$ is the area, $b$ is the base and $h$ is the height.

Step2: Substitute known values

We know that $A = 312$ m² and $h=24$ m. Substituting into the formula gives $312=\frac{1}{2}\times y\times24$.

Step3: Solve for $y$

First, simplify the right - hand side: $\frac{1}{2}\times24 = 12$, so the equation becomes $312 = 12y$. Then divide both sides by 12: $y=\frac{312}{12}=26$.

Answer:

26
