M Shade the bottom triangle. The area of a rectangle is A = bh. How does the area of a triangle with the same base and height relate to the area of the rectangle? A= h A = (5) (4) A= sq. units b That's the area of the rectangle. The area of the triangle is one-half the area of the rectangle, which gives us the formula for the area of a triangle: A=​

correct

step-by-step explanation:

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
