the length of a rectangle is four times it's width.if the perimeter is 70cm. Calculate the length and area of the rectangle​
Inga [223]

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

  • 7×28
  • 196cm²

hope it helps.

I need help on 1-8 ..
notka56 [123]

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.

Ira Lisetskai [31]
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:
x^{2} +30x-600=0
solving this quadratic equation you get a negative solution and a positive one that gives your result.
