Answer: 1.5x²
Step-by-step explanation:
Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.
Step 1: Find the length of the left side using the pythagorean theorem.
a^2 + b^2 = c^2.
x^2 + 2x^2 = 3x^2
√3x² = 3x
Step 2: Multiply the base times the hypotenuse.
x * 3x = 3x²
Step 3: Divide by two
3x²/2 = 1.5x²
