The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
Answer:
Base = 8
Step-by-step explanation:
Area of a triangle can be calculated as:
Area = 0.5 x Base x Height
The values of the area and the height are given in order to find the length.
A= 52 in^2
Height= 13
First we have to find the base or the length. Using the values above we can set up the equation as:
1. 52= (0.5)(13)(b)
2. 52/0.5(13)
3. b=8
Answer: The length of the guitar or the base would be 8 inches.
