Question

directions: study the information and figure, read each question, and choose the best answer.
a kindergarten student designs the following shape using blocks on the carpet floor.

1. what is the area of the triangular portion of the figure?

a. 12.5 m²
b. 25 m²
c. 50 m²
d. 59.63 m²

Explanation:

Step1: Recall the formula for the area of a triangle

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

Step2: Identify the base and height of the triangle

From the figure, the base \( b = 5\space m \) and the height \( h=5\space m \).

Step3: Substitute the values into the formula

Substitute \( b = 5\) and \( h = 5\) into \( A=\frac{1}{2}bh \). So, \( A=\frac{1}{2}\times5\times5\).

Step4: Calculate the area

\( A=\frac{25}{2}=12.5\space m^{2}\)

Answer:

A. \(12.5\space m^{2}\)
