Step-by-step explanation:
width of rectangle(w)=x let
length (l)=4x
perimeter of rectangle=70
2(l+w)=70
2(4x+x)=70
8x+2x=70
10x=70
x=70/10
x=7
again,
- length =4x=4×7=28cm
- width=x=7
area of rectangle =l×w
hope it helps.
Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
I found width=13.72 ft and length=43.72 ft.
Call one dimension of the rectangle x, the other will be x+30
You want an area A=600 ft^2 but A=length x width=x*(x+30)=600
Rearranging you get:

solving this quadratic equation you get a negative solution and a positive one that gives your result.
