Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the area of the triangle whose height is 36 m and the base is \$1/4\$th the length of the height. |
|
2 |
Step |
The given values are |
height = 36 m base is \$1/4\$ of length of the height |
3 |
Hint |
So here the base |
\$b = 1/4 \times "height"\$ |
4 |
Step |
Substitute the values |
\$b = 1/4 \times 36\$ |
5 |
Step |
After simplification |
9 m |
6 |
Formula |
Area of triangle |
\$A = 1/2 \times "base" \times "height"\$ |
7 |
Step |
Substitute the values |
\$ A = 1/2 \times 9 \times 36\$ |
8 |
Step |
After simplification |
162 sq.m |
9 |
Step |
The area of a triangle is A = 162 sq.m. |
