The perimeter of the triangle will be 41ft
<h3>The perimeter of a triangle</h3>
The perimeter of a triangle is the sum of all the sides of the triangle
From the given triangle, we need to get the third sidee firse as shown:
h² = 12² + 12²
h² = 144 + 144
h² = 288
h = 17ft
Perimeter = 12 + 12 + 17
Perimeter = 41ft
Hence the perimeter of the triangle will be 41ft

Answer:
The density of powdered sugar is 
Step-by-step explanation:
We are given that A student measures the mass of an 8 cm^3 block of confectioner’s (powdered) sugar to be 4.49 grams
Mass of block of confectioner’s (powdered) sugar = 4.49 grams
Volume of block = 8 cubic cm
We are supposed to find the density of powdered sugar.
So, 

Density =
Hence the density of powdered sugar is
