To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by 
. (This means you go from 
to 
.)
1/2 ÷ -3/7 = -7/6 The answer is -7/6
If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.
Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.
