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
Test your knowledge using the equation and check your answer with the calculator..
GRA = GW * GH/2 = ?
