Answer: 70.74
Step-by-step explanation:
A Nonagon has 9 equal sides, and each side of the given is 7.86
So 7.86 multiplied by 9 is 70.74
Answer:
+180
Step-by-step explanation:
Answer:
A = 624
B = 14.76 or 14.8 or 15inches
Standard form in polynomial for Area = 26 x 24 = .624in^2.....
2(5 + 8) x 2( 5 + 7)
26 x 24 = 624 in^2
This is because the rectangle width indifference is 1/10th of the length measuring 2inches more, then we see both sides of the frame are equal to 2inches and match this measure for x = 2inches both width and length. We add 4 to each side 22 x 20 + 4x^2 we separate 4x^2 into 4x both sides, this has become 26 x 24 = 624in^2
as 4 was added each side.
Question 2.
We find the width is shown left to right in rectangles, they are the sides.
So Area 4 x 24 = 96in^2
or 6.5 of the 24 = 24/6.5 = 3.69 inches
26 /6.5 = scale of 6.5: 26 = 4 inches
Therefore Area = 3.69 x 4 = 14.76
if it was square frame it would be 16inches
Go for 14.76in^2 as ithe question says 4 inches and it becomes, a replaced width only and it must be still to scale as shown above with 24/6.5 = 3.69 so 3,69 x 4 = 14.76. Last resort would be that the length as kept at 24 x 4 = 96 and in this response it does exactly what the question asks the width changes only.
Answer:
The playground covers 
of a square mile
Step-by-step explanation:
The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,
The area of the playground is length * width
Area = 
sq. mi
Hence the playground cover of a square mile
