Answer:
Height is 18 inches.
Base is 36 inches.
Step-by-step explanation:
Let the base of the triangular table top be x inches.
The height will be x inches.
The area of the triangular table top is 324 inches²
Area of a triangle = × Base × Height
342 inches² = × x × x
= 324
Finding the square root on both sides gives;
= 18
Therefore x (the base) = 36 inches
And (the height) = 18 inches.
