the perimeter of a parallelogram is 28 cm and ratio of the adjacent sides is 3:4 find the sides of a parallelogram?
let the adjacent sides of the parallelogram be 3x and 4x.
perimeter = 2*(3x+4x) = 2*7x = 14x
thus
thus the adjacent sides of the parallelogram are 3*2 and 4*2 i.e. 6 cm and 8 cm
since the opposite sides of the parallelogram are equal.
therefore the sides of the parallelogram are 6 cm , 8 cm , 6 cm and 8 cm .
hope this helps you.
cheers!!
