xy times yz divided by two is the area.
2a*a/2 is the area 36
a^2=36
a=6
xy is 12.
CHECK:
6*12=72
half of 72 is 36. Yeah!

What is a polygon with twice as many sides as a triangle and all your sides are the same length. what are you?
A regular hexagon
What type of triangle has one side twice as long as the other side?
A right triangle. * * * * * Not necessarily. All that can be said is that is is not an equilateral triangle. It can be isosceles or scalene. It can be acute angled, right angled or obtuse angled.
What is the perimeter in feet of a rectangle whose length is twice its width and whose width is 9 feet?
If the width is 9' and the length is twice that, the length is 18'; the perimeter is twice the length plus twice the width, which is 36' + 18' = 54 feet.
How do you calculate the length of a side of an equilateral triangle given the height?
Letting S represent the length of a side of an equilateral triangle having a height of 1 unit, then drawing a perpendicular from the mid point of a side to the opposite vertex creates a right triangle having sides 1, S, and ½S, with S being the hypotenuse of a right triangle. The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides; thus S2 = (H2 + (½)2S2) = 1 + ¼S2. Subtracting 1 from each side, S2 - 1 = ¼S2. Multiplying the terms on each side by 4, 4S2 - 4 = S2; subtracting S2 from each side, 3S2 - 4 = 0; adding 4 to each side, 3S2 = 4; dividing each side by 3, S2 = 4/3; Taking the square root of each side, S = 2/1.732 = 1.1547 The length of each side of an equilateral triangle is the product of 1.1547 x height. (Note: 1.1547 is twice the reciprocal of the square root of 3.) Example: if the height of an equilateral triangle is 30 cm, the length of each side will be 34.641cm (30 x 1.1547cm).
If the hypotenuse of a right triangle is 30 cm long and one leg is twice as long as the other how long are the legs of the triangle?
one leg is root300 which is close to 17.3 and the other is 2 times root300 close to 34.6
The area of a rectangle is 128 ft squared if the width is twice the length what is the measure of the length?
8 ft.
How to find the attitude of a triangle?
If you mean "altitude", and by that you mean the height of the top of the triangle above its base, then draw a line from the top of the triangle to the base, at right angles to the base, and measure that line. Alternately, the height of a triangle above its base is twice the area divided by the base length.
You are a polygon with twice as many sides as a triangle all of your sides are the same length what are you?
a hexagon
Consider a right triangle that has these dimensions The side opposite angle A is 6 meters and the side adjacent angle A is 8 meters. How long is the hypotenuse?
When two sides of a right triangle are 6 and 8, the triangle is similar to a 3-4-5 right triangle. Since 6 is twice 3 and 8 is twice 4, the hypotenuse has to be twice 5 or 10.

How many times can you fold a triangle?
Twice left to right right to left
In the pythagorean theorem is b twice of a?
In the Pythagorean Theorem b is not twice a. The formula is [ a squared + b squared = c squared].
What can be the ratio of the length of the longer leg of a 30-60-90 triangle?
the ratios in such a triangle are 1:2:sqrt(3) so the longest length is opposite the 90 degree angle and is twice as large as the length opposite the 30 degree angle
What is the base length of an isosceles triangle that two sides are 34 cm and the height is 30?
Draw a line joining the top vertex to the middle of the base. This divides the triangle into two right-angled triangles, which are congruent (both have the same side lengths and angles). Each right-angled triangle has a hypotenuse length of 34 cm (the hypotenuse is the side opposite the right angle). They also have a side which is the height of the triangle, 30 cm. By Pythagoras' theorem, the third side of each right-angled triangle is 16 cm long because 342 - 302 = 1156 - 900 = 256 = 162 The base of the isosceles triangle is twice that, so it's 32 cm long.

How would you construct a right triangle given the length of a leg and the radius of the circumscribed circle?
To construct a right triangle given the radius of the circumscribed circle and the length of a leg, begin with two ideas. First, the diameter of the circle is equal to twice the radius. That's pretty easy. Second, the diameter of the circle is the length of the hypotenuse. The latter is a key to construction. Draw your circle, and draw in a diameter, which is the hypotenuse of the right triangle, as was stated. Now set you compass for the length of the leg of the triangle. With this set, place the point of the compass on one end of the diameter (the hypotenuse of your triangle), and draw an arc through the circumference of the circle. The point on the curve of the circle where the arc intersects it will be a vertex of your right triangle. All that remains is to add the two legs or sides of the triangle. Draw in line segments from each end of the hypotenuse (that diameter) to the point where your arc intersected the curve of the circle. You've constructed your right triangle. Note that any pair of lines that is drawn from the ends of the diameter of a circle to a point on the curve of the circle will create a right triangle.
Area of triangle relates to the area of a rectangle?
Yes. Any triangle can be fitted twice into a rectangle having the same base length and vertical height as the triangle. Consequently, whilst the area of a rectangle = length x width ; the area of a triangle = 1/2 base x height. If we were using the same words this would be 1/2 length x width.
