Tributary Area given Roof Live Load Solution

Follow our step by step solution on how to calculate Tributary Area given Roof Live Load?

FIRST Step Consider the formula

A t = 1000 \cdot (1.2 - (\frac{L f}{20 \cdot R 2}))

Next Step Substitute values of Variables

∴

A t = 1000 \cdot (1.2 - (\frac{18.1N}{20 \cdot 0.9}))

Next Step Prepare to Evaluate

∴

A t = 1000 \cdot (1.2 - (\frac{18.1}{20 \cdot 0.9}))

Next Step Evaluate

∴

A t = 194.444444444444m²

Next Step Convert to Output's Unit

∴

A t = 2092.98258101014ft²

LAST Step Rounding Answer

∴

A t = 2092.9826ft²
