Question #fdcf3
1 Answer
Perimeter of the larger rectangle is
Perimeter of the smaller rectangle is
Explanation:
There are two possible answers to this question because there is no indication of whether the scaling factor is up or down.
When a dimension is scaled, its resulting size is usually much smaller than full scale so it can be represented by a drawing or scale model.
In this case the exercise may be to measure out a larger or smaller rectangle for use on a field.
We know the perimeter of the original rectangle is
We also know that the perimeter
And this means that if
The question also states that BOTH
This means the sum of the dimensions
It also means that the Perimeter is scaled by
Then if we upscale (enlarge) the dimension of a
Then if we downscale (reduce) the dimension of a
The answer can be tested by choosing some values for
Original:
Upscale:
Downscale:
