Can someone help with this. Heads up it's ratios

The median side measures 92 yards

Step-by-step explanation:

Let's call x, y, and z the measures of the sides of the triangle.

The ratios between them are:

The first ratio gives the relation:

The second ratio can be solved for z:

Since the perimeter is 299 yards:

Substituting the above relations:

Multiplying by 4:

Joining like terms:

Dividing by 13:

x=92

Now calculate y:

y = 161

z=46

The median side measures 92 yards

no this is a nonlinear negative

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2
