Let one llside be X cm
then another llside be( 5+X)cm
distance between them llsides =12cm
Area = 390
Area of trapezium = 1/2 ×(sum of llside) ×distance between llsides
390 = 1/2 (5+x+x) ×12
390 = (5+2x) × 6 [12÷2 =6]
390= 30 +1 2x
12x = 390-30
12x = 360
X = 360/12
x = 30
Now, one llside = x = 30pm
another llside = 5 +x =30+5 =35
