Short Answer

Expert verified

The area (螖) of given right angle triangle is15x2+25x2ft2 .

Step by step solution

01

Step 1. Write down the given information.

The given triangle is shown below with its parameter.

02

Step 2. Concept used.

The area (螖) of right-angle triangle having base (b) and perpendicular height (h) is given by the formula:

Area(螖)=12bh....(1)

03

Step 3. Calculation.

The area (螖)of given right angle triangle is evaluated as:

Area(螖)=12bh....(From(1))=12(3x+5)(5x)=15x2+25x2ft2

04

Step 4. Conclusion.

The area (螖) of given right angle triangle is15x2+25x2ft2 .
