The given dimensions of 9.5, 6, 7, and 6.5 cm gives the following
perimeter and area of the trapezium.
- Perimeter: <u>29 cm</u>
- Area: <u>49.5 cm²</u>
The perimeter of a trapezoid is given as follows;
Perimeter = The sum of the lengths of the sides
Which gives;
Perimeter = 6 + 7 + 6.5 + 9.5 = 29
The perimeter of the trapezoid =<u> 29 cm</u>
- Perimeter: 29 cm
The area of the trapezoid is given as follows;
Which gives;
The area of the trapezoid = 49.5 cm²
- Area:<u> 49.5 cm²</u>
