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)
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 = ?
