The face of a triangular shaped guitar has an area of 52 in.² and a height of 13 inches. write an equation to find the length of the base. then find the length of the base of the guitars face.

Area of a triangle can be calculated as:

Area = 0.5 x Base x Height

Area is given to be 52 in²
Height is 13 inches.
We are to find the base b of the triangular shaped guitar.

Using the values in above formula, we get:



Thus the base of triangular shaped guitar will be 8 inches. 

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
