Answer:
perimeter of trapezoid=40 units
Step-by-step explanation:
trapezoid can be divided in to square and right angle triangle
let ABCD be trapezoid and it is divided in to square ABED and right angle triangle BEC
BC=hypotenuse of right angle triangle
BC=hypotenuse=[tex]\sqrt{l^2+b^2}[/tex]
where l= BE and b=EC
given AB=8 units,CD=14 units
EC=14-8=6 units
AD=8 units
BC=[tex]\sqrt{8^2+6^2}[/tex]=10 units
perimeter of trapezoid=AB+BC+CD+AD
perimeter of trapezoid=8+10+14+8=40 units
perimeter of trapezoid=40 units answer
