If you know the area and the height of a triangle, how can you find the base.?

b = 2A/h

Step-by-step explanation:

The formula for area of a triangle is

A = 1/2 bh  where b is the base and h is the height

We want to find the base

Multiply each side by 2

2A = 2*1/2 bh

2A = bh

Divide each side by the height

2A/h = bh/h

2A /h = b

b = 2A/h

2 × Area ÷ height

Step-by-step explanation:

Area of triangle = ½ × base × height

base = 2 × Area ÷ height

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
