Question 528008
Area of the Court = A = 79.2 square meter
Length = L = W +4 m
Width = ?
Length = ?

Area of rectangle = Length * Width
A=L*W
79.2 = (W+4)W
79.2=w^2+4W
w^2+4W-79.2=0
Solve for 'w'

*[invoke quadratic "w", 1, +4, -79.2 ]

w=7.121 or w=-11.121 (inadmissible)

So w = 7.12

Length = L = W +4 = 7.12+4
Length = L = W +4 = 11.12 meter


Dimension of the Court
=====================
Length = 11.12meter
Width = 7.12meter
Area = 79.2 square meter
