Question

One side of a parallelogram is 2.5 m long er thanits adjacent side if the perimeter of the parallelogram is 51 m find the measure of all its sides

Answer 1

Let one side(l) = x and. other side (b) = x+2.5
Perimeter = 2 (l+b) = 2 (x + x + 2.5)
51 = 2 (2x + 2.5)
51 = 4x + 5
51 - 5 = 4x
46 = 4x. X = 11.5m = l
Other side = 11.5 + 2.5 = 14m

Answer 2

other side =11.5+2.5=14
