width of the rectangle = b = x
length of the rectangle = l = 8 + 2x
Perimeter of the rectangle = 70cm
Also, perimeter of the rectangle = 2(l + b)
70 = 2[x + (8 + 2x)]
70 = 2(x + 8 + 2x)
70 = 2(3x + 8)
70 = 6x + 16
70 - 16 = 6x
54 = 6x
54/6 = x
9 = x
Therefore, b = x
b = 9cm
l = 8 + 2x
I = 8 + 2×9
I = 8 + 18
I = 26cm

Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.
Step-by-step explanation:
When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A=
so we plug in our known variables...
we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.
r=9
A=
A=
81
A=254.469
