Based on my analysis of the image, I can provide a comprehensive explanation of how to solve the problem presented in the worksheet.
The image shows three worksheets titled "Calculating the Area of Triangles" (with Spanish translations). Each worksheet contains multiple triangles with some measurements provided, and students are instructed to calculate the area of each triangle.
Problem Solving Approach:
1.
Understand the Formula: The area of a triangle is calculated using the formula: Area = (base × height) ÷ 2
2.
Follow the Instructions:
- For the left worksheet: "Measure each side to the nearest tenth of a centimetre and calculate the area of each of these triangles."
- For the middle and right worksheets: "Measure the base and height of each triangle to the nearest centimetre. Calculate the area of each of these triangles."
3.
Process for Each Triangle:
- Identify the base and height of each triangle (these are perpendicular to each other)
- Measure them according to the instructions (to the nearest tenth of a cm for the left worksheet, or to the nearest cm for the middle and right worksheets)
- Apply the formula: Area = (base × height) ÷ 2
- Record the answer in square centimeters (cm²)
4.
Example Calculation:
If a triangle has a base of 4 cm and a height of 3 cm, the area would be:
Area = (4 × 3) ÷ 2 = 12 ÷ 2 = 6 cm²
Note: Since the image quality doesn't allow me to read the specific measurements clearly, I cannot provide the exact answers for each triangle. However, the process described above is what students would follow to complete this worksheet.
The worksheets appear to be designed for educational purposes, likely for elementary or middle school students learning geometry. The "ink saving Eco" label suggests these are environmentally friendly printables.
Parent Tip: Review the logic above to help your child master the concept of area of triangle worksheet.
