If a trapezoid has an area of 51 sq cm and a height of 6 cm with one of its parallels being 9 cm then what is the length of the other parallel?

Let the length of the other parallel be x:
1/2*(sum of the two parallels)*height = area
1/2*(9+x)*6 = 51 sq cm
Multiply both sides by 2 and then divide both sides by 6:
9+x = 17
Deduct 9 from both sides:
x = 8 cm
Check: 1/2*(9+8)*6 = 51 sq cm

What is the area of a trapezoid with a length of 7 height of 3 and a width of 12?
Area of a trapezoid = 0.5*( sum of parallel sides)*height
How do you find square feet of a trapezoid?
Find the total length of the parallel sides and divide the result by 2. Next, multiply that number by the height of the trapezoid.
Parallel sides of a trapezoid?
Called an Isosceles trapezoid when the sides that aren't parallel are equal in length.
What is the area of the trapezoid all length measure are in centimeters round the answer to one decimal place?
That depends on its dimensions of which none have been given but the area of a trapezoid is: 0.5*(sum of its parallel sides)*height
What is a trapezoid with even legs?
A trapezoid with even legs is a geometric shape where both of the non-parallel sides (or legs) are of equal length. The parallel sides, on the other hand, are not necessarily equal in length.
Is the area of a trapezoid equal to the products of the height and the length of the midsegment?
Area of a trapezoid = 0.5*(sum of parallel sides)*height
What is the area of a trapezoid with a length of 7 height of 3 and a width of 12?
Area of a trapezoid = 0.5*( sum of parallel sides)*height
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
Find the area of this trapezoid All length measures are in centimeters?
The area of a trapezoid is equal to the height, multiplied by the average of the two widths.
True or false the area of a trapezoid is equal to the product of the height and the length of the mid-segment?
False because the area of a trapezoid is: 0.5*(sum of its parallel sides)*height
What is area of a trapezoid if the width is 7 feet and the length is 38 feet?
Area of the trapezoid in square feet = 0.5*(sum of parallel sides)*height
How do you find square feet of a trapezoid?
Find the total length of the parallel sides and divide the result by 2. Next, multiply that number by the height of the trapezoid.
Does the area of the trapezoid double if the height double?
If the base length b and the top length a remain the same, then the area will double if the height his doubled.Area = ((a+b) x h ) / 2Please note that a trapezoid has the top a and base b parallel.
What is the area of a trapezoid?
The area of a trapezoid = 1/2 (altitude)(base 1 + base 2) *altitude can also be called the height, or the spacing between the parallel sides. Base 1 is the length of one of the parallel sides, and base 2 is the length of the other parallel side.
Parallel sides of a trapezoid?
Called an Isosceles trapezoid when the sides that aren't parallel are equal in length.
How do you find the area of a compound figure with there is a trapezoid and a rectangle?
Work out each figure separately then add them together: Area of a trapezoid = 0.5*(sum of parallel bases)*height Area of a rectangle = length*height
What is the formula in calculating square footage of a trapezoid?
A trapezoid has two parallel sides, and two that are not. Call the distance between the two parallel sides the height (H). Add the length of the two parallel sides (L1 + L2), multiple this by the height (H) and then divide by 2. This can be experessed as - ((L1 + L2) * H ) / 2 Remember, L1 and L2 are the length of the parallel sides, and H is the distance between the parallel sides. We do not care about the length or angle of the other sides.
