Sara's score in the sixth test is 98.
<h3>HOW TO CALCULATE TOTAL FROM MEAN?</h3>
The mean of a set of data can be calculated by dividing the total sum by the number of data given.
According to this question, Sara is said to have a mean score of 62 in 5 tests and another mean score of 68 in 6 tests.
- First total score = 62 × 5 = 310
- Second total score = 68 × 6 = 408
Therefore, Sara's score in the sixth test can be calculated by subtracting 310 from 408 to give 98.

Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = : = 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
