New perimeter = old perimeter*scale factor New area = Old area*scale factor2
# is the ratio of the demensions in the drawing to the corresponding actual dimensions. The scale factor for a scale drawing is the ratio of the dimensions in the drawing to the corresponding acual bimensions.
The scale factor is the ratio of any side of the image and the corresponding side of the original figure.
Here's how to do that: 1). Find its length. 2). Find its perimeter. 3). Divide (its length) by (its perimeter). The quotient is the ratio of its length to its perimeter.
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
The ratio of the length of the side in the big triangle to the length of the corresponding side in the little triangle is the scale factor.
The ratio of the perimeters is equal to the scale factor. If rectangle #1 has sides L and W, then the perimeter is 2*L1 + 2*W1 = 2*(L1 + W1).If rectangle # 2 is similar to #1 and sides are scaled by a factor S, so that L2 = S*L1 and W2 = S*W1, the perimeter of rectangle #2 is 2*(L2 + W2)= 2*(S*L1 + S*W1) = S*2*(L1 + W1) = S*(perimeter of rectangle #1).
divide the perimeter by 27 the multiply it by 3 and then u get the answer
well.... first off you have to find the scale factor...
The ratio of the volumes of similar solids is (the ratio of their linear dimensions)3 .
I highly doubt anyone knows. Perhaps, find a large map of Minnesota, estimate its perimeter (maybe by surrounding the border with string) then multiply by the proper scale factor.
A scale Factor is Algbrea so you have to... x - + and/or divided.
