On enlarging the rectangle, the proportion or ratio of Length to Height will stay the same.
The ratio of original length to height is 13 : 6
The ratio in enlarged rectangle will stay the same. Let the height of enlarged rectangle is y cm. So we can write:
Therefore, the height in enlarged rectangle will be 9 cm
Answer:
r = 3.2
Step-by-step explanation:
If A varies inversely with the square of r, then A = kr^2
75 = k*4^2 = 16k
k = 75/16
Now A = (75/16)*r^2
48 = (75/16)*r^2
r^2 = 48(16/75) = 256/25
r = = 16/5 = 3.2
The coordinates for C’ are (-30, 5)
