How do you express the area of a triangle as the function of its height?
A seamstress is designing a triangular scarf so that the length of the base of the triangle, in inches, is 7 less than twice the height, h. Express the area of the scarf as a function of the height.
I know the base would be 2h-7
and the height would be h.
But I have no idea where to go from there or how to express the area as a function of the height.
A = 1/2 * b * h
b = 2h – 7
A = (2h – 7) * h / 2
A = (2h^2 – 7h) / 2
That’s all it is.
A = 1/2 * b * h
b = 2h – 7
A = (2h – 7) * h / 2
A = (2h^2 – 7h) / 2
That’s all it is.
