Find the height of the trapezoid whose bases are 3.5 and 2.9 dm and the area is 2.56 dm²
| March 1, 2021 | education
We find the height of the trapezoid from the formula for the area of the trapezoid S = (a + b) * h / 2, the area of the trapezoid is equal to half the sum of the bases multiplied by the height.
From here, the height is h = 2S / (a + b), substitute the data and find the answer
h = 2 * 2.56 / 3.5 + 2.9 = 5.12 / 6.4 = 0.8 dm.
Answer: 0.8 dm.
