 Investigating the effect of enlargement on area and perimeter Posted on March 16, 2008 at 11:50 am by barbiegirlz and i carried out some investigations on several different shapes and came to the conclusion that to work out the area of a shape when you have only been told the original shape’s area and the scale factor of the new shape you must square the scale factor number. For example, if the original shape was 1cm2 and the new shape was sf (scale factor) 35 then the new shape’s area must be 1225cm2 (35 x 35) To find the perimeter (at least when the shape is a square) you must multiply the sf by 4. For example, if tou were given a 1x1cm square and told to find the perimeter of a new shape (35 sf of the original shape) you must multiply 35 by 4. The answer is 140cm. This is because the length of a original side is 1cm and there of 4 sides so the new shape is 35 times 1cm (35) times 4 (number of sides.) Geddit???
