first off let's recall that a square has all equal sides, so its area is just one side squared, namely A = s², or A = (s)(s).
we know the area is 16j² + 24j + 9, that simply means that two twin factors are in it, and it also means that the area polynomial is a perfect square trinomial.
You would divide 57 by 60, which equals 0.95. Move the decimal to get 95%
57.8 Divided by 81 is .714

Answer:
A) 106 ft^2
Step-by-step explanation:
The total surface area is the area of the base triangular face and the three lateral faces.
The base triangular face has length of its base to be b=6 ft.
The height of this triangle is 5.2 ft.
The area of this triangle is
to the nearest integer
The area of the three lateral face is
The total surface area is therefore 90+16=106 square feet
