Answer:
B) A rectangle with a length of 15 cm and a width of 9 cm
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
<em>Verify each cases</em>
case A) A rectangle with a length of 9 cm and a width of 6 cm
therefore
The rectangle case A) is not similar to rectangle A
case B) A rectangle with a length of 15 cm and a width of 9 cm
therefore
The rectangle case B) is similar to rectangle A
case C) A rectangle with a length of 14 cm and a width of 7 cm
therefore
The rectangle case C) is not similar to rectangle A
case D) A rectangle with a length of 12 cm and a width of 8 cm
therefore
The rectangle case D) is not similar to rectangle A
Answer:
70 students
Step-by-step explanation:
As, 30% Mike surveyed
And these 30% are 21 students
So 30% of X = 21
= 30/100 x X = 21
= 30X = 2100
So X = 2100/30
X = 70
So 70 students were surveyed
