On Your OwnPor tu cuenta
Tables, mistakes to find, and problems with a few steps.
Tablas, errores por encontrar y problemas de varios pasos.
- Fill in the table
- Match each shape to its area.
- A parallelogram has base 8 ft. Place a point on the number line at the height that gives an area of 48 sq ft. (Hint: A = b × h, so h = A ÷ b.)
- What is the best next move?
- Multiply the base by the slanted side: 15 × 9.
- Add the base and the height: 15 + 7.
- Use base × perpendicular height: 15 × 7.
- Multiply 15 × 7, then take half of it.
