A) 22 cm, 18 cm
B) 25 cm, 21cm
C) 29 cm, 25 cm
D) 27 cm, 23 cm
Correct Answer: D
Solution :
Let the lengths of the parallel sides of the trapezium be cm and b cm. Then, according to question, \[(a-b)=4\] ?(i) and \[\frac{1}{2}\times (a+b)\times 19=475\] \[\Rightarrow \] \[a+b=\frac{950}{19}=50\] ?(ii) By solving Eqs. (i) and (ii), we get a = 27 and b = 23 Thus, length of parallel sides are 27 cm and 23 cm.You need to login to perform this action.
