Ratio
------------------------------------------------------------------------------------
Width : Length
2 : 5
Let x be the scale factor
Width : Length
2x : 5x
------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5
------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x
Length = 5(5)
Length = 25
Width = 2x
Width = 2(5)
Width = 10
------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm

Step-by-step explanation:
An exponential function is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.
Answer:
0.79
Step-by-step explanation:
Hey mate
here is your answer
length and width are given in the ratio are ;(4:7)
area of rectangle = (l×b)
therefore,
4x×7x=700
28x^2=700
x^2=700/28
x^2=25
x=5
length =4x=4×5=20, lenght =20 and width =7x so, 7×5=35 width.....
