Question

what is the perimeter of this triangle? 7m 8m 10m p=?m

Explanation:

Step1: Recall the formula for perimeter

Perimeter of a triangle \( P=a + b+ c\) (where \(a\), \(b\), \(c\) are side - lengths).

Step2: Substitute the values

Here \(a = 7\), \(b = 8\), \(c = 10\). Then \(P=7 + 8+10\).

Step3: Calculate the sum

\(7+8 + 10=(7 + 8)+10=15 + 10=25\).

Answer:

\(25\)
