.'. the other 2 sides=x+2.5

.'. 2(x+2.5+x)=51

4x+5=51

4x=46

x=23

there fore x=23meters

x+2.5=25.5 meters

pls mrk brainliest

∴its adjacent side =x+2.5

perimeter of a parellelogram= 2(l+b)

=2(x+x+2.5)

=2(2x+2.5)

=4x+5

∴51=4x+5

∴4x=46

∴x=46/4

&∴x=11.5

∴one side of parellelogram =11.5

& its adjaccent side = 11.5+2.5=14

hope it helps and pls mark as best answer
