Question

perimeter is a measure of the distance around a figure. if each side of a triangle measures 0.75 inches, what is the perimeter of the triangle?
0.8325 inches
2.25 inches
15 inches
22.5 inches

Explanation:

Step1: Recall the formula for the perimeter of a triangle

The perimeter \(P\) of a triangle is \(P = a + b + c\). For an equilateral triangle (where \(a=b = c\)), \(P=3a\) (since all three sides are equal).

Step2: Substitute the value of the side length into the formula

Given \(a = 0.75\) inches. Using \(P = 3a\), we substitute \(a\): \(P=3\times0.75\).
Calculate \(3\times0.75=(3\times\frac{75}{100})=\frac{225}{100}=2.25\)

Answer:

B. 2.25 inches
