= <u>187.3 yards</u>

Step-by-step explanation:

The set-up will represent a triangle whereby the :

Width = Height = 150 yards
Diagonal = Hypotenuse = 240 yards
Length = Base = ?

${a}^{2} = {c}^{2} - {b}^{2} \\ {a}^{2} = {240}^{2} - {150}^{2} \\ {a}^{2} = 57600 - 22500 \\ \sqrt{ {a}^{2} } = \sqrt{35100} \\ a = 187.3yards \: (rounded \: off \: to \: 1dp)$
