Answer:
Step-by-step explanation:
The formula for the area of this triangle is
[tex]A=\frac{1}{2}bh[/tex]
Since we have a value for area, and we know that both the base and the height are x, then the formula can be rewritten as
[tex]27=\frac{1}{2}x^2[/tex]
Multiply both sides by 2 to get rid of the fraction to get
[tex]54=x^2[/tex]
Undo the square on the x by taking the square root of both sides. Rounding to the neareast tenth gives you that x = 7.3
