Perimeter is 2*L+2*W= 2*(L+W)
L=5*W-15
Perimeter=2*(5*W-15+W)=2*(6*W-15)
=12W-30=147 m ,147=12*W-30
147+30=12W , 12W=177 , W=177/12 L=5*(177/12)-15=(885/12)-(180/12)
=(705/12) L=705/12 Remark 15=(180/12)
Perimeter=2*(L+W)=2*((177/12)+(705/12))
=2*(882/12)=1764/12=147 m
the perimeter of a rectangle is 147 meters the length is 15 meters less than 5 times the width find the dimension
