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= $\pi r^{2}$ 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= $\pi 9^{2}$

A= $\pi$ 81

A=254.469

WILL.MARK BRAINLEST. ( The length of a rectangular garden is 5m longer than its breadth .If its perimeter is 150 m,find the area

inessss [21]

Answer:

1400m^2

Step-by-step explanation:

Solution,

Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,

Now,

Perimeter of the rectangle=2(l+b)

150=2(x+5+x)

150=2(2x+5)

150=4x+10

150-10=4x

140=4x

140/4=x

35=x

So, the breadth of the rectangle=35 m

and length=(35+5)m=40m

Again,

Area of the rectangle=l×b

=40m×35m

=1400 m^2
