the area of a triangle is 90 square meters and the height is 12 meters. What is the base of the triangle?

recall that the area of a triangle is

A = bh/2
b = base and h = height
substituting the values:
90 = b*12/2
90 = b*6
b = 15 meters

hope this helps~ :)

the area of a triangle is 90 square meters and the height is 12 meters. What is the base of the triangle

To find the base of a triangle when the area and height are given, you can use the formula for the area of a triangle:

Area = (base * height) / 2

Given that the area of the triangle is 90 square meters and the height is 12 meters, you can substitute these values into the formula:

90 = (base * 12) / 2

To solve for the base, you need to isolate it. Multiply both sides of the equation by 2:

2 * 90 = base * 12

180 = base * 12

Finally, divide both sides of the equation by 12 to find the base:

base = 180 / 12

base = 15

Therefore, the base of the triangle is 15 meters.
