## Gable Roof Area Formula

The following two example problems outline the steps and information needed to calculate the Gable Roof Area.

GRA = GW * GH/2

- Where GRA is the Gable Roof Area (ft^2)
- GW is the gable width (ft)
- GH is the gable height (ft)

To calculate the gable roof area, multiply the gable width by the gable height, then divide by 2.

## How to Calculate Gable Roof Area?

The following example problems outline how to calculate Gable Roof Area.

Example Problem #1:

- First, determine the gable width (ft).
- The gable width (ft) is given as: 30.

- Next, determine the gable height (ft).
- The gable height (ft) is provided as: 5.

- Finally, calculate the Gable Roof Area using the equation above:

GRA = GW * GH/2

The values provided above are inserted into the equation below and computed.

GRA = 30 * 5/2 = 75.00 (ft^2)

Example Problem #2:** **

For this problem, the variables required are provided below:

gable width (ft) = 60

gable height (ft) = 10
