Question

2
15ft
20ft
12ft
25ft
area =
perimeter =

Explanation:

Step1: Calculate the area

The formula for the area of a triangle is \(A=\frac{1}{2}\times base\times height\). Here, the base is \(25\) ft and the height is \(12\) ft.

$$ A=\frac{1}{2}\times25\times12 $$

$$ A = 150\space ft^{2} $$

Step2: Calculate the perimeter

The perimeter of a triangle is \(P=a + b+ c\), where \(a = 15\) ft, \(b = 20\) ft, \(c = 25\) ft.

$$ P=15 + 20+25 $$

$$ P=60\space ft $$

Answer:

Area \(= 150\space ft^{2}\)
Perimeter \(= 60\space ft\)
