the area of a triangle is 27 sq ft. its height is 3 times the length of the base. find the height and base.
1 answer:
let base be x
height = 3x
area = 1/2 * base* height
area = 1/2 * x*3x
Area = 3x^2/2= 27
3x^2= 54
x^2= 54/3
x^2= 18
x= sqrt 18
x= sqrt (3*3*2)
x= 3sqrt2 the base
height = 3 * 3sqrt2
height = 9 sqrt2

B is 1/4 the size is of triangle A. The corresponding sides have a 4:1 ratio.
I believe it’s A because if it is perpendicular you would have to flip 6X and change the sign so therefore it would be A. In slope intercept form it would be y=-6x+1.
