Let 
be the side length of the small square. Then, the side length of the big square is 
.
The respective areas are 
and 
So, the sum of the areas are 
We have
We can't have negative lengts, so we choose 
So, the side length of the larger square is 6.
Number one is D
number 2 is A
No because when you cross multiply 9/24 has a bigger number
the formula for perimeter is l+l+w+w
So 9+9+6+6= 30 meters of fence
Answer:
The first thing you need to do is, have a square whose area is 11² = 121 square inches. Then we are going to multiply the radius by π which is 3.14 the area of the circle with the radius 4 is equal to 3.14 × 4² = 3.14 × 16 = 50.24, you need to divide the calculated radius times π (3.14) you can get the answer and you need to round your answer to the nearest hundredth probability that the dart will hit within the circle is equal to 50.24 ÷ 121 = 0.4152066116 which is rounded to 0.04152 or 41.52% this assumes the dart will always hit the square at least.
