it xoild be 8 anfd 12
Ratio of new length to old length = 12/8 = 3/2 So ratio of new width to old width must be 3/2 New width/Old width = 3/2 so New width = Old Width * 3/2 = 6 inches*3/2 = 9 inches
The area of a rectangle is length times width. If length and width are in inches, the area will be square inches.
It is decreased by half. If you decrease the width by half and leave the length alone, you get the same result.
perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15
Area = length x width Length = area/width
2/1

times the length by the width
Beautiful. You copied the set-up and the suggestion perfectly, but skipped the question. Anyway, the answer is 10. Now all you have to do is find the question again.
Then the width has to be 9 in
9 inches7.5 inches wide
