Question

the floor of a rectangle banquet hall has an area of 3,600 m2. The length is 90m. What is the width of the banquet hall?

Answer 1

Data:
A (area) = 3600 m²
L (lenght) = 90 m
W (width) = ?

Formula:
$A = L*w$

Solving:
$A = L*w$
$3600 = 90*w$
$3600 = 90w$
$90w = 3600$
$w = \frac{3600}{90}$
$\boxed{\boxed{w = 40\:m}}\:\longleftarrow\:Width$
