Answer:
942 cubic feet
Step-by-step explanation:
Answer:
2800000
Step-by-step explanation:
10^6 means 1000000
2.8 x 1000000 = 2800000
Answer:
none of them
Step-by-step explanation:
Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
We know that
[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x
Area=x*y-------> x*(122-x)----> 122x-x²
find the derivative function and equals to zero
122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m
<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
