How do you work out the lengths of the parallels of a trapezoid when one base is 1.5 cm greater than the other and has a height of 16 cm with an area of 212 square cm?

Suppose the smaller side is x cm
Then the greater side is x+1.5 cm
The area is 0.5*(sum of parallel sides)*height
So 0.5*(x+x+1.5)*16 = 212
ie 8*(2x+1.5) = 212
2x + 1.5 = 212/8 = 26.5
2x = 25
x = 12.5
and then the other side is x+1.5 = 14
The sides are 12.5cm and 14cm

What is the height of an isosceles trapezoid if the bases are 8 and 12?
With the information given it can be any height greater than zero units. If the area was given, or the lengths of the equal sides were given, then the height can be calculated specifically.
How you could find the height of a trapezoid if you knew the length of the 2 bases and the area of the trapezoid?
Height of trapezoid = 2*area/sum of parallel sides
What is the formula for a trapezoid?
The perimeter of a trapezoid is the sum of the lengths of each side. To find the area of a trapezoid: add base 1 and base 2 together then divide that answer by 2, then multiply it by the height of the trapezoid.
Area of trapezoid?
A=h(b+B) divided by 2 * * * * * where A = area h = vertical height b and B are the lengths of the parallel sides.
What is the area of a trapezoid with base lengths of 8 and 11 and height of 10?
Area of the trapezoid: 0.5*(8+11)*10 = 95 square measurements
How do you find the height a trapezoid?
It is the distance between the parallels
What is the area trapezoid with lengths of 71137?
Area of a trapezoid = 0.5*(sum of parallel sides)*height
What is the height of an isosceles trapezoid if the bases are 8 and 12?
With the information given it can be any height greater than zero units. If the area was given, or the lengths of the equal sides were given, then the height can be calculated specifically.
How do you find the height of a trapezoid when area given?
If the lengths of the bases are also given then rearrange the area of the trapezoid formula so that the height is the subject.
How you could find the height of a trapezoid if you knew the length of the 2 bases and the area of the trapezoid?
Height of trapezoid = 2*area/sum of parallel sides
What is the formula for finding trapezoid?
The formula for finding the area of a trapezoid is (a + b) * h / 2, where a and b are the lengths of the parallel sides, and h is the height of the trapezoid.
What is the formula for a trapezoid?
The perimeter of a trapezoid is the sum of the lengths of each side. To find the area of a trapezoid: add base 1 and base 2 together then divide that answer by 2, then multiply it by the height of the trapezoid.
What is area of trapezoid?
The area of a trapezoid is equal to half the sum of the lengths of the two parallel sides (base1 and base2) multiplied by the height. The formula for the area of a trapezoid is A = (base1 + base2) * height / 2.
How do you get the height of the trapezoid if you only have the area?
Divide area by one half of the sum of the bases. You need to know base lengths to get height
What is the area of a trapezoid with base lengths 3 feet and 9 feet and a height of 4 feet?
The answer is 24.
How do you find height of a trapezoid?
A trapezoid is a polygon. Therefore, a trapezoid has no height
How do you figure out the area of a trapazoid?
-- Add the lengths of the two 'bases' (the two parallel sides). -- Multiply the sum by the height of the trapezoid. -- Take 1/2 of the product. That's the trapezoid's area.
