Answer:

b = 4 inches and h = 14 inches

Step-by-step explanation:

Given that,

The area of a triangle, A = 28 sq inches

Height is twice less than 4 times the base.

H = 4b-2, b is base

We know that,

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}bh\\\\28=\dfrac{1}{2}\times b\times (4b-2)\\\\56=4b^2-2b\\\\28=2b^2-b\\\\b=4\ inches,-3.5\ inches[/tex]

Base = 4 inches

Height = 4(4)-2

= 14 inches

Hence, this is the required solution.
