Answer:
Step-by-step explanation:
It is given that A triangular pane of glass has a height of 30 inches and an area of 270 square inches , thus
\(Area of triangle=\frac{1}{2}{\times}base{\times}height\)
Substituting the given values, we get
\(270=\frac{1}{2}{\times}b{\times}30\)
\(270=15b\)
\(b=18\)
Therefore, the length of the base of triangular pane is 18 inches.
