Question

let the width of rectangle FRAN equal w. The rectangle is 4cm less than the width. In the rectangle IREN the width is 7 more than w and the length is 2 less than 3 times w. if their perimeters are equal, find w.

Answer 1

Your question doesn't make sense:
"The rectangle is 4cm less than the width."?

Answer 2

sorry typo it was the LENGTH of the rectangle is 4cm less than the width

Answer 3

perimeter of fran we call A=
2(w+L)=2[w+(w+4)]=4w+8
perimeter of iren we call B=
2(w+L)=2[(w+7)+(3w-2)]=8w-10
A=B
4w+8=8w-10
4w=18
w=4.5
pretty sure I got it
