Your family has decided to put a rectangular patio in your backyard similar to the shape of your backyard. Your backyard has a length of 50 feet and a width of 25 feet. The length of your new patio is 16 feet. Find the perimeter of your new patio.

If shapes are similar than ratios between their corresponding measurements should not change
L1/W1=L2/W2
50/25=16/W2
W2=(25*16)/50=16/2=8 ft
P of a new patio= 2*(L2+W2)=2(16+8)= 48 ft
