How to rewrite area formulas?

So I have no idea how to get the normal formula for area of a triangle (a=1/2xbxh) into a formula so that the missing variable wouldn’t be area, it would be the base. So the formula should start with b= not a=. How do I do this?
a = (1/2)bh
b = a/([1/2]h)
b = 2a/h
Answer: b = [...]

How to find Length of the base of a triangle if Area= 36 cm(sq’d) & base has a 90 degree angle?

Each angle of the triangle is labeled as follows beginning left to right beginning with base: X,Y,Z. Angle ‘Y’ is a 90 degree angle. The area of the triangle is 36 cm squared. Need to find the length of leg XY. Answers were: A. 6, B. 9, C. 12, D. 18, F. 24. Can anyone [...]

Express the hypotenuse h of a right triangle given the area as a function of the perimeter?

Express the hypotenuse h of a right triangle with area 25m^2 as a function of it’s perimeter p.
How would I do this? Thank for helping!
Call A=25 the area.
Call a and b the sides (and their length) adjacent to the right triangle.
We have:
1) Area: A = ab/2, so that ab = 2A
2) perimeter: p = a [...]

How do you create a quadratic equations with this formula: "Area=Length x Width"?

I’m doing a project on quadratic equations, and the question says, "Graph the length and area of each rectangle (length on the horizontal axis and area on the vertical axis)." I’m pretty sure that since this project is on quadratic equations, I have to graph a quadratic equation concerning the formula above, but I dont [...]

Do you guys believe that the "area 51" shown on google maps is the real one?

I believe mo its just to shady and dead… If anything might be located beneath ground
It is real. You can’t hide 80 acres of land from a satellite. There are tunnels located around Area 51.

Software which will calculate the area under a graph? Or triangle area?

Hi, I have 4 or so graphs to calculate the area of. I am willing to redraw them digitally.
Is there any software which will give me a numerical value for the area under the triangle of each graph?
Or the area of each triangle I draw?
Thanks.
