Answer: the ratio of the perimeters = 7/9
the ratio of the areas = 47/81
Explanation:
The scale factor of the two triangular mats is 7 / 9. Expressing it in terms of decimal fraction, it becomes 0.778
Perimeter is the total distance around the triangle. It is determined by simply adding the length of each sides. Therefore it is a linear measurement. Therefore, the ratio of the perimeter of both triangles will remain 7/9 or 0.778
The area of the triangle is not a linear measurement. Determining the area of the triangle involves multiplication of the different lengths by applying the desired formula. The ratio of the areas of both triangles will be (7/9)^2 = 47/81
