Question

A square garden has the dimensions shown:

Which of these polynomials could be used to represent the perimeter of the garden?

a) 4x^2-3x+9/16
b) 8x+3
c) 16x^2+3x+9/64
d) 4x^2+3x+9/16

Answer 1

The perimeter is the distance `around` the garden.
So if each side length is \(\large \left(2x+\dfrac{3}{4}\right)\)

Then the perimeter will be the sum of all 4 sides,
\(\large \left(2x+\dfrac{3}{4}\right)+\left(2x+\dfrac{3}{4}\right)+\left(2x+\dfrac{3}{4}\right)+\left(2x+\dfrac{3}{4}\right)\)

Or in other words,
\(\large 4\left(2x+\dfrac{3}{4}\right)\)
