Chapter 9, Problem 3STP

To determine

To calculate:To calculate the area of a right-angled triangle, where base is $5x^2$ and the height is $2x$ .

Answer to Problem 3STP

The correct answer is $A.$$5x^3$

Explanation of Solution

Given information:

Given base is $5x^2$ and the height is $2x$ of a right-angled triangle.

Formula Used:

Area of a right-angled triangle is given as −

  $Area=\frac{1}{2}\times base\times height$

Calculation:

Given base is $5x^2$ and the height is $2x$ of a right-angled triangle.

Using the formula for area of a right-angled triangle, we have:

  $Area=\frac{1}{2}\times 5x^2\times 2x$

Solving the above expression, we have:

  $Area=$$5x^3$

Thus, the area of the right-angled triangle is $5x^3$ .

Conclusion:

The correct answer is $A.$$5x^3$
