Problem |
A right-angle triangle has a length of 2 adjacent sides of 6 meters and 8 meters, find the perimeter of the triangle |
|
2 |
Step |
The two adjacent sides sides are given |
6 meters & 8 meters |
3 |
Step |
Now, You can use the Pythagorean theorem to find the length of the hypotenuse. |
\$c^2 = a^2 + b^2\$ |
4 |
Step |
Now,substitute the values |
\$c^2 = 6^2 + 8^2\$ |
5 |
Step |
After simplification |
\$c^2 = 36 + 64\$ \$c^2 =100\$ |
6 |
Step |
Apply square root on both sides |
\$\sqrt(c^2) = \sqrt(100)\$ |
7 |
Step |
After cancellation |
c = 10 unit. |
8 |
Step |
Now that you have the lengths of all three sides of the triangle, you can find the perimeter (P) by adding them together: |
P = a + b + c |
9 |
Step |
Substitute the values |
P = 6 + 8 + 10 |
10 |
Step |
After simplification |
P = 24 meters |
11 |
Solution |
So, the perimeter of the right-angled triangle is 24 meters. |

13 |
Choice-A |
This is the correct answer for the perimeter of the triangle |
Correct 24 meters |
14 |
Choice-B |
This is not correct because it represents the length of just one side (the hypotenuse) and not the perimeter of the triangle |
Wrong 30 meters |
15 |
Choice-C |
This is not correct because it represents the length of just one side (the hypotenuse) and not the perimeter of the triangle |
Wrong 10 meters |
16 |
Choice-D |
This is not correct because it represents the length of just one side (the hypotenuse) and not the perimeter of the triangle |
Wrong 11 meters |
