10. A rentangle has width the same as a side of a square whose perimeter is 20m. the length of the rectangel is 9 M. Find the perimeter of this rectangle.

W=L+20m

2L+w=9

2L+2w(w-18)=84

2L+2w-18=84

4L+18=84

4L=18-84

4L=66

L=66/4

Each side of the square must be 5 m (20/4).

The rectangle's measurements are 5 m x 9 m.

P = 2W + 2L

P = 10 + 18

P = ____________
