Question

1. what is the area of a triangle with a base equal to 10 cm and a height equal to 5.7 cm?

Explanation:

Step1: Recall triangle area formula

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

Step2: Substitute values into formula

Given base \( b = 10\space\text{cm} \) and height \( h=5.7\space\text{cm} \), substitute into the formula:
\( A=\frac{1}{2}\times10\times5.7 \)

Step3: Calculate the result

First, \( \frac{1}{2}\times10 = 5 \), then \( 5\times5.7=28.5 \).

Answer:

The area of the triangle is \( 28.5\space\text{cm}^2 \).
