Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
What is the area of a trapezium when bases are 16 cm and 30 cm respectively, and the distance between the two parallel sides is 20 cm? |
|
2 |
Step |
The length of the bases are given |
16 cm & 30 cm |
3 |
Step |
The height is |
20 cm |
4 |
Formula |
To find the area of a trapezium, you can use the formula: |
\$"Area" = (1/2) \times ("sum of the lengths of the bases") \times ("height")\$ |
5 |
Step |
Now plug the values into the formula |
A = \$1/2 \times (16 + 30) \times 20\$ |
6 |
Step |
After simplification |
A = \$1/2 \times 46 \times 20\$ A = \$23 \times 20 = 460\$ |
7 |
Step |
So, the area of the trapezium is 460 square centimeters. |
