Question

Express the area A of a right triangle as a function of the base b if the height of the triangle is twice its base

This is what the answer is supposed to Look like

A( )=( )

Fill in the blanks..

Thank you guys so much,

ten points to the correct answer and helping me understand how you got it.

Answer 1

in general area = base* height ...right

so know read the problem again...

first you know that the area your trying to find is a right triangle..so it is half a box right....if you dont undertand this google "right trianle" so you can see a picture. so what ever you get divide it by 2

then,

the base = b

also you know that the height or h is twice the base ...you can right this as h=2b....right

finally put everything together,,,

A= bh=b*2b= 2b^2, but because its a right triangle you divide it by 2.  (this i area is for a box)

A= (2b^2)/2

so,

A(b,h)= b^2

dam...im good
