Question

Can someone explain how to find the area of a triangle? I know it’s A=bh but I don’t really get how to find the base and height.

Answer 1

To find the area of a triangle, you need to know its base and height. The formula for the area of a triangle is:

A = 1/2 * b * h

where A is the area, b is the base of the triangle, and h is the height of the triangle.

In your case, if the base of the triangle is 18 feet and the height is 20 feet, you can find the area by plugging these values into the formula:

A = 1/2 * 18 feet * 20 feet

A = 180 square feet

So the area of the triangle is 180 square feet.

To clarify, the height of the triangle is the perpendicular distance from the base to the opposite vertex. In your example, the height of the triangle is 20 feet because the line segment connecting the bottom left corner of the triangle to the top point is perpendicular to the base, and it measures 20 feet. The base of the triangle is the horizontal line segment at the bottom of the triangle, and it measures 18 feet.

Answer 2

A = 180 ft²

Explanation:

the area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the perpendicular height )

here b = 18 and h = 20 , then

A =
`(1)/(2)` × 18 × 20 = 9 × 20 = 180 ft²
