The difference between two parallel sides of a trapezium is 4 cm.
Question 1:
The difference between two parallel sides of a trapezium is 4 cm. perpendicular distance between them is 19 cm. If the area of the trapezium is 475
A.27 and 23
FeedbackLet the two parallel sides of the trapezium be a cm and b cm. Then, a - b = 4 And, 1/2×(a+b)×19=475=>(a+b)=50 Solving (i) and (ii), we get: a = 27, b = 23. So, the two parallel sides are 27 cm and 23 cm
B.24 and 23
C.25 and 23
D.22 and 23
