Respuesta :
The length of the rectangle yard is; L = 12ab³
We are given;
- Area of rectangular yard; A = 72a³b⁴ ft²
- Width of rectangular yard; w = 6a²b
Now, formula for area of a rectangle is;
A = L × w
Where;
L is length
w is width
- Thus;
L = A/w
Plugging in the relevant values gives;
L = 72a³b⁴/6a²b
L = (72/6) × (a³/a²) × (b⁴/b)
L = 12ab³
