A trapezoid has an area of 45 cm2 The two bases are 6 cm and 12 cm What is the height of the trapezoid?
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 500 cm3 in cm2?
To convert volume (cm3) to area (cm2), you need to divide by the height or length of the object. Since volume is a three-dimensional measurement and area is two-dimensional, you need an additional dimension to make the conversion. Without knowing the height or length of the object, it is not possible to convert 500 cm3 to cm2 accurately.

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
