Answer:

A. 7605

Step-by-step explanation:

If a number is divisible by 9, it is also divisible by 3.

A number is divisible by 9 if the sum of its digits equals 9 or an integral multiple of 9.

A. 7605

7 + 6 + 0 + 5 = 18 (an integral multiple of 9) ; divisible by 9.

B. 7690

7 + 6 + 9 + 0 = 22 ; not divisible by 9

C. 5390

5 + 3 + 9 + 0 = 17 ; not divisible by 9

B. 4524

4 + 5 + 2 + 4 = 15 ; not divisible by 9

The only number divisible by 3 and 9 is 7605.

Answer:

92 feet.

Step-by-step explanation:

Given:

The length of the garden needs to be 22 feet longer than the width of the garden.

The perimeter of the fence is a total of 324 feet

Question asked:

What will the length be of garden ?

Solution:

As length of the garden needs to be 22 feet longer than the width,

Let width = $x$

Then, length will be = $x+22$

As here perimeter of the fence is given, we can find length and width of garden by using:

Perimeter of rectangle = $2(length+width)$

$324=2(x+22+x)\\324=2(2x+22)\\324=4x+44\\$

Subtracting both sides by 44

$324-44=4x+44-44\\280=4x\\$

Dividing both sides by 4

$70=x$

Width = $x$ = 70 feet

Then, length will be = $x+22$ = 70 + 22 = 92 feet

Therefore, the length of the garden will be 92 feet.
