Question

In an Isosceles Trapezium PQRS, PR = (5x + 2) and QS = (8x-7 cm - ) then find the length of PR.

  1. 20    
  2. 18    
  3. 17    
  4. 15    

hintHint:

diagonal of isosceles trapezium are equal

The correct answer is: 17


    d i a g o n a l space o f space i s o s c e l e s space t r a p e z i u m space a r e space e q u a l
P R space equals space Q S
5 x plus 2 space equals space 8 x space minus 7
3 x space equals space 9
x equals 3
P R space equals 5 asterisk times 3 space plus 2 space equals space 17
