2 3/4a=9 1/4
2.75a= 9.25
cross off 2.75 and a will remain
divide 9.26 and 2.75
so a=3.36363636
a=<span>3.36363636
but you can round it to a=3.4ish i guess</span>

The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 mete

Answer:

5 meters

Step-by-step explanation:

If the smallest rectangle has a length of 8 meters, and a perimeter of 24 meters then its width is given by:

$24 = 2*8+2*W_1\\W_1= 4\ meters$

We can conclude that the width is half of the length for both rectangles. Therefore, the width of the larger rectangle, with a perimeter of 30 meters, is:

$30 = 2*W_2+2*L_2\\30 = 2*W_2+4*W_2\\W_2=5\ meters$
