The basic types of lessons about perimeter, area, volume of geometries send to the students for reference as follows:

🌱 2.1. Find the area of a triangle with base equal 42.5cm and height equal 5.2cm

🌱 2.2. To make a triangular road sign needs 22.4dm2 of metal. Its height is 54cm. Find the corresponding base of the sign.

🌱 2.3. A trapezium has 2 bases: 9.4m and 6.6m; and the height is 10.5m. Find the area in square meter.

🌱 2.4. A trapezium-shaped garden has the average of 2 bases equal 125dm and the height is 150dm. Find the area of the garden in square meter.

🌱 2.5. A circular well has radius equal 3.2dm. Find the circumference of the well.

🌱 2.6. A trapezium-shaped field has the long base equal 150m and the short base equal 3/5 of the long base. The height equals to the average of 2 bases. People grow rice on the field and harvest 65kg of rice in every 100 m². In total, how many tons of rice can be harvested in the field?

🌱 2.7. Find the total surface area of a cube with its side equal to 7.2dm

🌱 2.8. Cubes with side equal 1cm are used to build a cuboid of 12cm x 8cm x 6cm. How many cubes are needed?

🌱 2.9. Each brick is 30cm long, 20cm wide and 0.5cm high. Each box contains 24 bricks. Find the volume of the box.

🌱 2.10. 960 cubes with side equal 1cm are arranged as a cuboid with 12cm in length and 10cm in width. 6 faces of the cuboid are painted. How many cubes are painted in only 1 face?

Hope they will actively study to achieve the best results.
