Find the area of an isosceles trapezoid whose height is 16 cm and the diagonals are mutually perpendicular.
September 23, 2021 | education
| We recall the theorem according to which if in an isosceles trapezoid the diagonals are mutually perpendicular, then its height is equal to the half-sum of the bases. Therefore, the half-sum of the bases is 16 cm.
The area of the trapezoid is found as the product of the half-sum of the bases and the height. We know all the data, we calculate the area:
S = 16 * 16 = 256 cm2 – the area of an isosceles trapezoid.
Answer: The area of an isosceles trapezoid is 256 cm2.
