Question

finding the area of triangles
the base (b) of the triangle is units.
the height (h) of the triangle is units.
the area of the triangle is square units.

Explanation:

Step1: Determine the base and height

From the grid, count the units. The base \(b = 4\) units (horizontal side) and the height \(h= 2\) units (vertical side as it is a right - triangle).

Step2: Use the area formula for a triangle

The formula for the area of a triangle is \(A=\frac{1}{2}bh\). Substitute \(b = 4\) and \(h = 2\) into the formula: \(A=\frac{1}{2}\times4\times2\).
First, calculate \(4\times2=8\), then \(\frac{1}{2}\times8 = 4\).

Answer:

The base \((b)\) of the triangle is \(4\) units. The height \((h)\) of the triangle is \(2\) units. The area of the triangle is \(4\) square units.
