Answer: Square, 24 square inches

Step-by-step explanation:

Given

Diameter of round pizza d=16\ in.

Side of square pizza a=15\ in.

Area of circle \pi r^2

The area of a square is a^2

\therefore \text{Area of round Pizza}=\pi \times (\frac{16}{2})^2\\\Rightarrow A_1=\pi \times 8^2=201.088\ in.^2

The area of square pizza is

A_2=15^2=225\ in.^2

Clearly, the area of square pizza is more and the difference in their area is

\Rightarrow A_2-A_1=225-201.088=23.91\approx\ 24\ in.^2

ValentinkaMS [17]
L×w=64 ft^2...(1)
2w+8= l...(2)

l=64-w...(1a)

2w+8= 64-w
2w+w+8=64
3w=64-8
3w÷3= 56÷3
w=18.6'

l×w= 64
l×18.6= 64
l= 64÷18.6
l= 3.44 to the nearest hundredths.
