( operatorname{lem} g+h=(3 n-5 z) ) unile
Perimeter of a nectangle ( 2(1 e n g+h+b) ) readth ( Rightarrow 2(3 n-52+mid text { readth })=5 x-9 y+2 z )
( Rightarrow quadleft(3 x-5 z+text { bre ad }+h=frac{5}{2} x-frac{9}{2} y+2right. )
( Rightarrow ) Ineadth ( =frac{5}{2} n-frac{9}{2} y+2-(3 n-5 z) )
bueadth ( 2 frac{5}{2} x-3 n-frac{9}{2} y+2+5 x )
( frac{7-5 u-6 u}{2}-frac{9}{2} y+7 z )
( left(-frac{x}{2}-frac{9}{2} y+7 zright) ) units

# 6. Find the perimeter of the triangle whose sides are (3x+4y=z) units, (+47 ) ums and (44 4 ) units. If the perimeter of the rectangle is (5x-9y+ 2z) units and its length is (3x - 5z) units, find its breadth. 8. What must be subtracted from 15mnt - 24nt to get 23mnt + 2nt??
