Trapezium

Raju wants to make a trapezium-shaped solar panel on his house rooftop. If the length of two parallel sides of the roof is 7m and 10m and the distance between two parallel sides is 10m.

How does the shape of a solar panel impact its efficiency in capturing sunlight?

Learning Objectives:

1. Derive the formula for finding the area of the trapezium.

2. Apply the concept to solve problems related to real-life  situations.

LO :

 1)Derive the formula for finding the area of a trapezium

  2) Apply the concept to solve problems related to real-life situations.

Arrange the two trapezium to form a parallelogram and observe the dimensions and

complete the activity sheet.

Imagine your table top as a rectangular surface that needs a design makeover. Your task is to transform it into a trapezium shape.
1.Measure the length and width of your rectangular table top and calculate the area.
2.Redesign the table top in to a trapezium by adjusting one of its shorter sides, making it shorter than the other and calculate the area.

A table top is in the shape of a trapezium. The parallel sides are 3m and 4m and the distance between the two parallel sides is 2m.Find the area of the table.

1. 14 sq.m
2. 7 sq.m
3. 28 sq.m
4. 24 sq.m
