Answer:
40 feet
Step-by-step explanation:
We are given a right isosceles triangle having lengths of two sides 12 feet and 16 feet.
<em>Since, the triangle is an isosceles triangle i.e. two sides of the triangle are equal.</em>
That is, the three sides of the triangle are 12 feet, 12 feet and 16 feet.
We know that, Perimeter of a triangle = Sum of the sides
Thus, Perimeter of the given triangle = 12 + 12 + 16 = 24 + 16 = 40 feet.
Hence, the total length of the fencing needed is 40 feet.
