Question

what is the area of this triangle? 42in squared 83in squared 21in squared 36in squared

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify the base and height

From the diagram, the base of the right triangle is $6$ in and the height is $7$ in.

Step3: Substitute the values into the formula

Substitute $base = 6$ and $height = 7$ into the formula: $A=\frac{1}{2}\times6\times7$.
First, calculate $6\times7 = 42$. Then, $\frac{1}{2}\times42 = 21$.

Answer:

21in squared
