Find the perimeter and the area of the figure. A right-angled trapezoid has a shorter base of 7 centimeters, longer base of 9.5
laila [671]

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>

<h3>How can the area and perimeter of the trapezium be found?</h3>

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;

Area = \mathbf{ \dfrac{Sum \ of \ the \ parallel \ sides }{2} \times Height}

Which gives;

Area = \dfrac{7 + 9.5 }{2} \times 6 = 49.5

The area of the trapezoid = 49.5 cm²

  • Area:<u> 49.5 cm²</u>
