The area of a trapezoid is equal to one half the product of the length of its height and the sum of its bases. So we have:
A = (1/2)(h)(B + b) substitute what you know into the formula
45 cm^2 = (1/2)(h)(12 cm + 6 cm)
45 cm^2 = (1/2)(h)(18 cm)
45 cm^2 = (h)(9 cm) divide by 9 cm to both sides
5 cm = h
Thus, the height is 5 cm.

What is the area of an isosceles trapezoid that has bases of length 22 and 9 centimeters and legs of length 14 centimeters?
Vertical height = sqrt{142 - [(22-9)/2]2} = sqrt{142 - 6.52} = sqrt(153.75) = 12.40 cm (approx).So area = 1/2*(22+9)*12.40 = 192.19 cm2.Vertical height = sqrt{142 - [(22-9)/2]2} = sqrt{142 - 6.52} = sqrt(153.75) = 12.40 cm (approx).So area = 1/2*(22+9)*12.40 = 192.19 cm2.Vertical height = sqrt{142 - [(22-9)/2]2} = sqrt{142 - 6.52} = sqrt(153.75) = 12.40 cm (approx).So area = 1/2*(22+9)*12.40 = 192.19 cm2.Vertical height = sqrt{142 - [(22-9)/2]2} = sqrt{142 - 6.52} = sqrt(153.75) = 12.40 cm (approx).So area = 1/2*(22+9)*12.40 = 192.19 cm2.

What is the area and perimeter of a right-angled trapezoid whose bases are 17cm and 8cm with a height of 6cm?
Area = 1/2*(17+8)*6 = 75 cm2 Use Pythagoras' theorem to find the sloping side of the trapezoid: 62+92 = 117 and the square root of this is about 10.8 Perimeter = 17+8+6+10.8 = 41.8 cm
How do you find the unknown height of a trapezoid if the bases are 27cm and 31 cm and the area is 348cm2?
You can cut the tapered ends off of the trapezoid, and calculate the individual areas of the three pieces. The center piece is a rectangle, Length = 27, Height = H. Area = 27H. Each end is a triangle, Base = 2, Height = H. Area = (1/2 base) times (height) = 1H (Left-end triangle) + (center rectangle) + (right-end triangle) = 1H + 27H + 1H = 29H. 29H = 348 cm2 H = 348/29 = 12 cm

The base is 11cm area 82.5 cm2 how do you find the height of the triangle?
half the base an divide the area by that
How do you find the height of the prism with the volume of 275 centimeters and the area of the base of 25 centimeters?
volume_of_prism = area_of_base x height 275 cm3 = 25 cm2 x height => height = 275 cm3 / 25 cm2 = 11 cm
