g = 0.7

Step-by-step explanation:

To isolate g, we do the same thing to both sides.

Dividing both sides by 25 gives us:

g = 17.5/25

g = 0.7

H = 59.4

Step-by-step explanation:

The question is an illustration of dilation.

From the small shape, we have:

Body = 3

Height = 2.2

From the big shape, we have:

Body = 81

Height = ??

Because it is a dilation, the ratio of the bodies must be equal to the ratio of the heights

i.e.

$Body_{Small} : Body_{Big} = Height_{Small} : Height_{Big}$

Substitute the right values

3 : 81 = 2.2 : H

Express as fraction

$\frac{3}{81} = \frac{2.2}{H}$

$\frac{1}{27} = \frac{2.2}{H}$

Make H the subject

H = 2.2 * 27

H = 59.4

Hence, the height of the big shape is 59.4 units
