The length and br

Perimeter = 336m

Let length of the field be L, and breadth be B.

Perimeter of a rectangle = 2(L + B) = 336

Or L + B = 168

Given

3L = 4B

Or L =

Substituting the above result in L + B = 168,

On solving, we get B = 72

And since 3L = 4B, L = 96

Area = L × B = 96 × 72 = 6912m²
