Answer:
take the width as x
Step-by-step explanation:
here it is said that length is 15 cm more than width so I don't know the length and and width
so I take the width as x and it is then said that the length is 15 cm more than x so length is 15x
and accoding to the formula of perimeter
perimeter = 2*(length +breadth )
so let's do make the equation
2*(15x+x) = 150
2*16x =150
32x = 150
x= 150 /32
x= 5
