| Let’s make an equation, according to the formula, to determine the area of a rectangle, denoting the largest side as x, S = 48 m²:

S = a * b, therefore:

x * 3 / 4x = 48. Let’s perform actions with the coefficients of the variable:

3 / 4x² = 48.

Therefore, x² = 48: ¾ = 48 * 4/3 = 64.

x = √64 = 8 m.

The length of such a figure is 8 m, and the width = 8: 4 * 3 = 2 * 3 = 6 m.
