Isosceles 5666

In the isosceles trapezoid ABCD, calculate the missing side length "a" and its areas. Side b = d = 50 cm, c = 20 cm, height = 48 cm.

Correct answer:

a =  48 cm
S =  1632 cm2

Step-by-step explanation:

b=50 cm d=50 cm c=20 cm v=48 cm x=b2v2=502482=14 cm a=c+2 x=20+2 14=48 cm
S=(a+c)/2 v=(48+20)/2 48=1632 cm2
