Answer» Let the width be x.then length be x+4A/Q-l+b=36x+(x+4)=362x+4=362x=36-42x=32x=16.Hence, The length of garden will be 20 m and width willbe 16 m. perimeter =2 (l+b)half peri. 36m= (l+b)let breadth=xlength= 4xperimeter= 2×36= 72mperimeter = 2 (l+b)72= 2 (4+x+x)36= 4+2x36-4=2x32= 2x32/2=x16=xbreadth=16length= x+4=16+4=20 perimeter = 2( l+b); half peri=36m=( l+b); breadth=x; length=4x; perimeter=2×36=72 m; 36=4+2x; 36-4=2x; 32=2x; x=32/2=16 = breadth; length=x+4=16+4=20 |
