We need to fond the last missing side of this right triangle.
We need to use pythagorean theorem.
a^2 + b^2 = c^2
In this problem,
a = 10
b = ?
c = 14
Plug these numbers into the equation.
10^2 + b^2 = 14^2.
Square each term.
100 + b^2 = 144.
Subtract 100 from each side.
b^2 = 44.
Take the square root of each side.
b = 7 ft
we have to add together each side of the triangle to find the perimeter
10ft + 7ft + 14ft = 31 feet
The perimeter is 31 ft
