Step-by-step explanation:
Given 2 similar figures with ratio of corresponding sides = a : b
Then the ratio of the perimeter is also = a : b
and ratio of areas = a² : b²
Here ratio of sides = 2 : 5, thus
ratio of perimeters = 2 : 5 and
ratio of area = 2² : 5² = 4 : 25
There are 13 students in Sara's class. I did this by using 8 = 3/5x, x being the total number of students. The answer is 13.33334 but you cant have half a student so it rounds down to 13.
also number 4 can be any positive number. This is because if you take one fourth of a negative number it will be more than if you doubled it. for example 1/4 of -4 is -1 which is more than -4 doubled which is -8
