Answer:
w =4 ft and l =10 ft
Step-by-step explanation:
Let w = width
l = 2w+2
A = l*w
A = (2w+2)(w)
40 = (2w+2) w
Distribute
40 = 2w^2 +2w
Subtract 40
0 = 2w^2 +2w - 40
Dividing each side by 2
0 = w^2 +w -20
Factor
0 = (w+5) (w-4)
Using the zero product property
w+5 =0 w-4=0
w= -5 w=4
Since we cant have a negative length
w=4
l = 2w+2 = 2(4)+2 = 8+2 =10
We have to round each whole number to the given place value.
We have to round the number 437 to the tens place.
Since the digit at the tens place is 3.
Since the digit at its previous place that is ones place is '7' which is greater than 5.
Therefore, we can round the number 437 to 440.
Now, consider the another number 64,328, we have to round this number to the nearest ten thousand place.
Since the digit at ten thousands place is 6.
And the digit at its previous place that is, at thousands place is 4.
Since this number is less than 5.
Therefore, the given number will round to 60,000.
