Perimeter = sum of its 4 sides Area = 0.5*(sum of 2 parallel sides)*height
1/2*(sum of parallel sides)*height = area height = (2*area) divided by (sum of parallel sides)
-- 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.
When it's a right triangle and it's sitting on one of the congruent sides.
If you draw another altitude parallel to the height (the side which is perpendicular to the bases) of the trapezoid, you can see that a right triangle is formed.In this triangle the hypotenuse length is 17 in, and the base length equals to 28 - 16 = 12 in. From the Pythagorean theorem, height length = √(17 - 12) ≈ 12 in.Or find the measure of the angle (call it A) opposite to the height such as:cos A = 12/17A = cos-1 (12/17) ≈ 45⁰, which tells us that this right triangle is an isosceles triangle.Therefore, the height is (congruent with base) 12 inches long
It is the distance between two congruent parallel faces.
1/2*(sum of both parallel bases)*height = area multiply both sides by 2 and then divide both sides by (sum of both parallel bases) height = (2*area) divided by (sum of both parallel sides)
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
Perimeter = sum of its 4 sides Area = 0.5*(sum of 2 parallel sides)*height
The base is the bottom of the figure and the height is how tall the figure is.
70 square inches
1/2*(sum of parallel sides)*height = area height = (2*area) divided by (sum of parallel sides)
False...

All solid figures have length, width and height and, conversely, if a figure has length, width and height then it is a solid figure.
