Question

area = ________________
find the area of a triangle using
b = 14 meters
h = 20 meters
(image: triangle with base 16 km, height 6 km (dashed line, right angle))

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area \( A \) of a triangle is \( A=\frac{1}{2}\times b\times h \), where \( b \) is the base and \( h \) is the height.

Step2: Substitute the given values into the formula

We are given that \( b = 14 \) meters and \( h=20 \) meters. Substituting these values into the formula, we get \( A=\frac{1}{2}\times14\times20 \).

Step3: Perform the calculation

First, calculate \( 14\times20 = 280 \). Then, multiply by \( \frac{1}{2} \): \( \frac{1}{2}\times280=140 \).

Answer:

The area of the triangle is \( 140 \) square meters.
