The area (in square centimeters) of a square coaster can be represented by d^2+8d+16 .
Katarina [22]

ANSWER

a. d+4

b. 4d+16

EXPLANATION

The area of the square coaster is represented by:

{d}^{2}  + 8d + 16

We split the middle term to obtain,

{d}^{2}  + 4d + 4d + 16

We factor by grouping to get,

d(d + 4) + 4(d + 4)

(d + 4)(d + 4) =  {(d + 4)}^{2}

Since area of a square is l² , it means the side length of the square is

l = d + 4

b) The perimeter of a square is given by

P=4l

We substitute the length in terms of d, to obtain;

P=4(d + 4)

Or

P=4d + 16
