the perimeter of a||GM is 280cm one is less than the other by 10cm find the length of the sides of the ||gm
Answers
Step-by-step explanation:
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 = 280
or 4 X = 280+20 = 300
Therefore X will be 300 / 4 =75
One side will be 75 cm Therefore other side will be 75 - 10 = 65
if we add 75 + 75 + 65 + 65 we get 280 which is perimeter given in the question.
