The adjacent sides of a parallelogram are in the ratio 3 : 4, If the perimeter of a parallelogram is 84cm, find out its sides. |
|
Answer» Step-by-step explanation: LET the sides be 3x cm. and 4xcm. so,perimeter =2( 3x + 4x)cm =(2×7x)cm = 14X cm. Now, perimeter of llgm.= 84cm ( GIVEN) so, by the problem, 14x= 84 or,x=84÷14 =6 so ,x=6 3x cm.= (3×6)cm.= 18cm 4xcm.=(4×6) cm=24 cm. thus,the sides are 18cm and 24cm respectively.....
