Step-by-step explanation:
We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.
The correct answer is C.
I will help you but I don't understand the equation. Can you please write it differently. Is it 4^2 x-3=12 or 4^2x - 3 =12

Factorize using the difference of squares identity.

Then

Step-by-step explanation:
Perimeter of a square = 4 × L
L = Length of a side of the pond = 30m
Perimeter = 4 × L = 4 × 30 = 120m = 12,000 cm
Pace = 60cm
Number of paces = 12,000/60 = 200 paces
