The height of a triangle is 4 times it’s base. The area of the triangle is 392 square centimeters. Find the base and height of the triangle.

Area of triangle, a=392[Given]

Let the base of triangle be x and height be 4x.

According to question:-

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
