Question

Please help me find the area of the triangle in terms of x!

Answer 1

`Solution,\\Area~of~triangle=(1)/(2) (base)(height) = (1)/(2)(2x+(1)/(4)) (x-8)\\~~~~~~~~~~~~~~~~~~~~~~~~ =(1)/(2)[2x^2-16x+(1)/(4)x-(1)/(4)(8)]\\ ~~~~~~~~~~~~~~~~~~~~~~~~ =(1)/(2)[2x^2-(63)/(4)x - 2]\\~~~~~~~~~~~~~~~~~~~~~~~~=x^2-(63)/(8)x-1`
