What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 5.5?
Perimeter = 50 cm, area = 155.25 cm2
Perimeter = 50 cm, area = 1,452 cm2
Perimeter = 154 cm, area = 155.25 cm2
Perimeter = 154 cm, area = 1,452 cm2
Also, the rectangle is 6 Length and 8 width

Perimeter is the total sum of the side of a polygon. Rectangles perimeter is 2(lengths) + 2(width). The area for the Rectangle is length x width
So would I be doing 12 times 18?
I don't understand what the 2 means
Not the answer you are looking for? Search for more explanations.
err 12 times 16 my bad
For the perimeter:
(2 x length) + (2 x width)
your length is 6 and your width is 8.
yes, 12 and 16 but you have to add these two together
and since the question says it is scaled by 5.5 , you have to multiply their sum by 5.5
I was multiplying my bad
it's okay :)
so what is 12 + 16?
all added together and multiplied by 5.5 is 154
yes, that's right, so that will be your perimeter.
Next is the area which is simply : length x width , what will you get?
48 which enlarged by 5.5 is 264
are you sure?
each dimension is enlarge, so it should be:
(5.5 x 6) x (5.5 x 8)
Thats what i did wrong
so the answer is D Thank you
For the perimeter, it is okay to multiply the answer at the end because we are just adding the dimensions but for the area, we have to multiply each dimension because we need to multiply them.
And you're welcome :)
