what is the mathematical sentence in the photo?
Answer (1)
Answer:To find the height of a triangle given the base and area, we use the formula for the area of a triangle:Step-by-step explanation:[ A = \frac{1}{2} \times \text{base} \times \text{height} ]Given:Base ((b)) = 18 mArea ((A)) = 90 dm² = 9 m² (since 1 dm² = 0.01 m²)Rearranging the formula to solve for height ((h)):[ h = \frac{2A}{b} ]Substitute the given values:[ h = \frac{2 \times 9}{18} = \frac{18}{18} = 1 , \text{m} ]So, the height is 1 meter.
