Question

what is the area of this triangle? 128 cm squared 32 cm squared 28 cm squared 16 cm squared

Explanation:

Step1: Find the base length

The base of the triangle is the sum of the two segments, so \( 4 + 4 = 8 \) cm.

Step2: Recall the area formula for a triangle

The formula for the area of a triangle is \( A=\frac{1}{2}\times base\times height \). Here, the height is 8 cm (from the diagram) and the base is 8 cm.

Step3: Calculate the area

Substitute the values into the formula: \( A = \frac{1}{2}\times8\times8 \)
First, calculate \( 8\times8 = 64 \), then \( \frac{1}{2}\times64 = 32 \) \( cm^2 \).

Answer:

32 cm squared
