Q4. Sides of a parallelogram are in the ratio 4,5 if the perimeter of a parallelogram is 180 am then find its length and breadth...Want with explanation...Pls​

Answer 1

perimeter of parallogram=2(length+breadth)

ad=bc

ab=dc..(opposite side are congruent

2(4x+5x)=180

8x+10x=180

18x=180

x=10

4×10=40

5×10=50

length of perimeter is 50 cm

breadth =40 cm
