The hight of the step is 

h ≥ 8 inches

If we take that in one feet we have twelve inches

The hight between floors are H=10ft = 120 inches

If we named number of steps with n, the appropriate inequality is

n ≤ 120/8 => n ≤ 15 

Good luck!!!!

A) Find the area<br>B) Find the perimeter ​
Archy [21]

Answer:

A)

A1= 64

A2= 40

B)

P= 56(of whole shape)

Step-by-step explanation:

A squares area is a side squared so 8^2= 64, and it is also shown that a side of the square is the base of the parallelogram. The area of a parallelogram is b*h so (square side)(8) * height(5)= 40.

Since a parallelograms opposite sides are congruent, 8+8=16, and the other two sides need to be congruent and equal to 40-16(24), therefore the sides are both 12.

Then to calculate the perimeter just count up the side lengths, 8+8+8+12+8+12=56

Answer:

44 strawberries to 77 blueberries
