What the area of 7.6km and 5km

the area of a triangle = 19 km²

Step-by-step explanation:

area of a triangle = 1/2 b h

where b = 5km

h = 7.6 km

plugin values into the formula:

A = 1/2 (5) 7.6

A = 19 km²

therefore,

the area of a triangle = 19 km²

this is false ^.^ lol

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
