Answer:
False.
Step-by-step explanation:
The formula that is used to find the area of a rectangle is given by :
A = l×b
Where,
l is length and b is breadth
If area of a rectangle is 6m², it means we need to find the factors of 6. The factors of 6 are 2 and 3. If we multiply 2 and 3, we get 6.
Other possibility can be 1 m by 6 m because if we muliply 1 m and 6 m, we get 6m².
It means there are more than one possibiliy about the length and breadth of the rectangle.
Hence, the given statement is not true.
Answer:
x=6
Step-by-step explanation:
h(x) = -( x-2)^2 +16
We want when h(x) = 0
0 = -( x-2)^2 +16
Subtract 16 from each side
-16 = -( x-2)^2 +16-16
-16 = -( x-2)^2
Divide by -1
16= ( x-2)^2
Take the square root of each side
±sqrt(16) = sqrt(( x-2)^2 )
±4 = x-2
Add 2 to each sdie
2 ±4 = x-2+2
2+4 = x 2-4 =x
6 =x -2 =x
since time cannot be negative
x=6
length = 22 cm; width = 18 cm
length = 24 cm; width = 16 cm
length = 23 cm; width = 14 cm
Answer:
Length = 25 cm , Width = 15 cm.
Step-by-step explanation:
Given : The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 80 cm.
To find : What are the dimensions of the rectangle.
Solution : We have given
Perimeter = 80 cm .
According to question :
Let width of rectangle = W .
Length is twice its width.
L = 2W .
Length of a rectangle is 5 centimeters less than twice its width.
L = 2W - 5.
Then ,
Perimeter = 2 ( length + width).
Plug the values
80 = 2 ( 2W - 5 + W ) .
80 = 2( 3W -5) .
On dividing both sides by 2
40 = 3W - 5 .
On adding both sides by 5.
45 = 3 W .
On dividing both sides by 3.
W = 15 cm .
L = 2W - 5.
L = 2 ( 15) - 5 .
L = 30 -5 .
L = 25 cm .
Therefore, Length = 25 cm , Width = 15 cm.
