Rectangular trapezoid

The rectangular trapezoid ABCD is: /AB/ = /BC/ = /AC/. The length of the median is 6 cm. Calculate the circumference and area of a trapezoid.

Correct answer:

o =  26.9282 cm
S =  41.5692 cm2

Step-by-step explanation:

s=6 cm s=(a+c)/2  c = a/2 6 = (a+a/2)/2 a=12/(1+1/2)=8 cm  b=a=8 cm c=a/2=8/2=4 cm  a2 = d2 +(a/2)2  d=a2(a/2)2=82(8/2)2=4 3 cm6.9282 cm  o=a+a+c+d=8+8+4+6.9282=26.9282 cm
S=d s=6.9282 6=24 3=41.5692 cm2
