Problem page the length of a rectangle is four times its width. if the perimeter of the rectangle is 70 cm , find its area.

agasfer [191]

So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.

I hope I helped!

Answer:

$B_2=4\pi r^2$

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

$B=\pi r^{2}$

where

r is the radius of the circular base

If the radius is doubled

then

$r=2r$

The new base area is

$B_2=\pi (2r)^{2}$

$B_2=4\pi r^2$

$B_2=4B$

therefore

The new area of the base is 4 times the area of the original base
