Grade: 1400-a Lesson: S3-L5 |
Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Calculate the area of a rhombus having diagonals equal to 9 cm and 6 cm. |
|
2 |
Step |
Given diagonals are |
p = 9 cm , q = 6 cm |
3 |
Formula: |
Area of a Rhombus is |
A = \$ ("p" \ times "q") / 2\$ |
4 |
Step |
Substitute the values into the formula |
A = \$ (9 \times 6)/2\$ A = \$54/2\$ A = 27 |
5 |
Step |
So, the area of a rhombus is \$ 27(cm)^2\$ |
|
6 |
SumUp |
Can you summarize what you’ve understood in the above steps? |
|
7 |
Choice.A |
Incorrect option units - problem specifies cm, not m |
\$ 27(m)^2\$ |
8 |
Choice.B |
This is incorrect because the calculated area is \$27 cm^2\$, not \$25 cm^2\$ |
\$25 cm^2\$ |
9 |
Choice.C |
This is incorrect because the calculated area is \$27 cm^2\$, not \$24 cm^2\$ |
\$24 cm^2\$ |
10 |
Choice.D |
The answer is accurate, correctly representing the rhombus area with the provided diagonals |
\$ 27(cm)^2\$ |
