The lens equation is 1f=1p+1q, where f is the focal length of the lens, p is the distance of the object from the lens, and q is the distance of the image from the lens. the formula to find q is

The required formula is .

Step-by-step explanation:

The given equation is

where,

1. f is the focal length of the lens.

2. p is the distance of the object from the lens.

3. q is the distance of the image from the lens.

We have to rearrange the formula for q.

Multiply both sides by fpq.

Subtract fq from both the sides.

Take out the common factor q.

Divide both the sides by (p-f)

Therefore the required formula is .

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
