The area of a square is
(length of a side) times (length of a side) .
So if you want to know the length of the side,
you have to find a number that gives you 81
when you multiply the number by itself.
That's called the "square root" of 81 .
Each side of your square is 9 units long.
S= (pi times r times l) + (pi times radius squared)
Factor out the pi times r
S= (pi times r) l + r
Divide
S/(pi times r)= l + r
Find common denominator and subtract
(S- pi times r)/(pi times r) = l
The answer therefore is A
2000 cm^2
Step-by-step explanation:
we simply round the dimensions of 50.8 cm to 50 cm and 40.6 cm to 40 cm, and we multiply 50*40 cm to get to 2000cm^2 (it is squared because this is area)
