Sorry! OK. I'll make this quick. Formula: A= A+B+C+D
A= 134 cm2
B= 170 cm2
C= 202cm2
D= 238 cm2
So, just add them altogether.
A= 744 cm (But I don't know what the exponent would be. Sorry!) I think that is how it would be. Its been a while since of done Area, though. Sorry about not knowing the exponent. And sorry if this isn't acurate.
ANSWER

EXPLANATION
We use the formula

For

and n=8, r=4.

This simplifies to

We expand the numerator using factorial notation,

The common factors cancel out.


5
because 5 goes 5 times into 25 also its a square root of 25 hope this helped <span />
In order to find this out, let's convert both of them into percents. Since 17.5 is already a percent, we only have to convert 1/6 into a percent. To convert 1/6 into a percent, you have to divide the numerator by the denominator. If you do that, you will get 0.1666..... as a repeating decimal. Now, multiply the decimal by 100 or just move the decimal 2 spaces to the right to get the percent. If you do that, you will get 16.6%. Since it is a repeating decimal, you can round it to 16.7%. So, 17.5% is larger than 1/6.
Hope it helps :)
Actual area = 42ft²
The actual area will simply be calculated as:
= 6 × 7
= 42 feet²
