Answer:
length 10
Step-by-step explanation:
If we hace a width of x then the length is 2.5x. The perimeter of the rectangular portrait is the sum of all sides then: x+x+2.5x+2.5x as we know the perimeter is 28 then:
[tex]x+x+2.5x+2.5x=28[/tex]
[tex]2x+5x=28[/tex]
[tex]7x=28[/tex]
[tex]x=\dfrac{28}{7}=4[/tex]
As x is the width to know the length we have to multiply 4 by 2.5 then the length is 10.
