The answer rounds up to 14,000 because it is more than half of the numbers 13,000 and 14,000.
Width of the rectangle is 13 cm and length is 29 cm.
<u>Step-by-step explanation:</u>
Step 1:
Given perimeter of the rectangle = 84 cm. Let the width be x, then the length of the rectangle = 2x + 3. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.
84 = 2(2x + 3 + x) = 2(3x + 3) = 6(x + 1) [taking 3 as common factor outside)
⇒ 84 = 6x + 6
⇒ 78 = 6x
∴ x = 13
⇒ Width of the rectangle = 13 cm
∴ Length of the rectangle = 2x + 3 = 29 cm
Answer:
Step-by-step explanation:
The points A and B have coordinates at (0,4) and (4,2) respectively.
The distance formula can be used to find the length of AB.
Since quadrilateral ABCD was enlarged with a scale factor of 
.
The length of A'B' is
Given :
If a number is tripled , it give same result as 28 is added to.
To Find :
We need to find that number.
Solution :
Let, the number is x.
Mathematical equation of the given scenario is :
3x = x + 28
3x - x - 28 = 0
2x - 28 = 0
x = 14
Therefore, the which give such result is 14.
