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(w18)=84
2L+2w18=84
4L+18=84
4L=1884
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 = ____________
