Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
The base of an acute-angled triangle with an area of 24 sq. units and base 8 units is needed to calculate its height. |
|
2 |
Step |
The area of a triangle is given, |
24 sq.units |
3 |
Step |
The base of a triangle is given, |
8 units |
4 |
Step |
Now, we have to find the height of a triangle. |
|
5 |
Formula |
Area of a triangle |
A = \$1/2 \times "base" \times "height"\$ |
6 |
Step |
Now, we have to find the height of a triangle. |
|
7 |
Step |
Now plug the values into the formula |
24 = \$1/2 \times 8 \times "h"\$ |
8 |
Step |
After simplification the value we get |
48 = \$8 \times "h"\$ |
9 |
Step |
Divide 8 on both sides. |
\$cancel48^6/cancel8^1\$ = \$cancel(8h)^1/cancel8^1\$ h = 6 |
10 |
Step |
So,the height of a triangle is 6 units. |
