Question

The length of a parallelogram is 2.5 metre longer than its adjacent side if the perimeter of the parallelogram is 15 metre find the measure of all its side

Answer 1

Answer:

Adj.side x m

length x +2.5m

Perimeter=2x+2(x + 2.5) = 15m

2x+2x+5=15

4x=10

x=2.5m

Adj. side=x=2.5m

Length=2.5+2.5=5m

sides=5,2.5,5 and 2.5. m
