Trapezoid circuit area

A right-angled trapezoid has parallel sides of 9 cm and 50 mm, and the shorter leg is 3 cm long. Calculate the perimeter and area.

Final Answer:

o =  22 cm
S =  21 cm2

Step-by-step explanation:

a=9 cm c=50 mm cm=50:10  cm=5 cm d=3 cm  b=(ac)2+d2=(95)2+32=5 cm  o=a+b+c+d=9+5+5+3=22 cm
S=2a+c d=29+5 3=21 cm2
