a rectangle's length is 5cm less than its width. if the length is decreased by 5cm and width is increased by 2cm the perimeter is 74cm . find the length and width

Answer 1

length of rectangle is 17.2cm and width is 19.2cm

Answer 2

rect length x-10
rectangle width y+2
perimeter 2(l+b)
2(x-10+y+2)=74
2x-10+y+2=74
2x-10+y=74-2
2x+y=72+10
x+y=82/2
x+y=41
