What is the circumference of quadrilateral ABED in cm?
Natasha2012 [34]

the perimeter of quadrilateral ABED is 36.

<h3 /><h3>What is circumference?</h3>

A circumference is the total distance around a plane shape. Another name for circumference is called perimeter

To calculate the circumference of the quadrilateral, we use the formula below.

Formula:

  • Peri. of ABED = /AB/+/BE/+/ED/+/DA/............. Equation 1

From the Diagram,

Given:

  • /AB/ = /DC/ = 8 cm,
  • /BE/ = 2×/DA/ = 2×6 = 12 cm
  • /ED/ = √(6²+8²) = √(36+64) = √100 = 10 cm
  • /DA/ = 6 cm

Substitute these values into equation 1

  • Peri. of quadrilateral ABED = 8+12+10+6
  • Peri. of quadrilateral ABED  = 36 cm

Hence, the perimeter of quadrilateral ABED is 36.
