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
