the perimeter of a parallelogram is 280 cm if its adjacent sides are in the ratio 3:4 then find the lenghts of all 4 sides of the parallelogram |
|
Answer» let ONE side be X CM then other side will be X - 10 .it is a parallelogram therefore the two opposite sides will be EQUAL &perimeter is sum of all sides therefore X + X +X-10 + X-10 = 280or 4 X = 280+20 = 300Therefore X will be 300 / 4 =75One side will be 75 cm Therefore other side will be 75 - 10 = 65if we add 75 + 75 + 65 + 65 we get 280 which is perimeter given in the question. |
