Height #color(blue)(h = 4x^3 + 18)#

Explanation:

Area of triangle #A = (1/) b h# where b is the base and h the height.

#h = (2 * A) / b#

Given : #A = 14x^5 + 7x^2# & #b = 7x^2#

#:. h = 2 * (14x^5 + 63x^3 / (7x^2#

#=> (2 * cancel(7x^2)(2x^3 + 9)) / cancel(7x^2)#

#h = color (blue)(2(2x^3 + 9) => color(blue)(4x^3 + 18)#
