How do i find the amount of a tringle if the sides of the triangle measures 23.66 feet, 23.66 feet and 22.8 feet?

Step-by-step explanation:

If two sides are the same (two sides measure 23.66) this means the triangle is an isoceles triangle. The equation for area of an isoceles triangle is as follows:

x base x height.

As you have the size of the base, you need to find the area of the height.

As this turns into a pythagoras' theory question, you need to reacall:

To get the b^2 value we need to divide the total base (22.8) value in two:

22.8 ÷ 2 = 11.4

So, as you have the hypotenuse () and the base () we need to find the value.

To do this we need to subtract the value from the value:

Plug the values in:

So

Simply square root this to find a:

a = 20.7325

Now we have all the possible value, we need to plug them into the area formula which was:

x base x height

Plug the values in:

= 230.6505
