The length is 6.8 meters and the width is 8.2 meters.

<h3>How to determine the dimension of the room?</h3>

Represent the length and the width with x and y

So, we have:

y = 1.2x

P = 2(x + y)

The perimeter is 30.

So, we have:

2(x + y) = 30

Divide by 2

x + y = 15

Substitute y = 1.2x

x + 1.2x = 15

This gives

2.2x = 15

Divide by 2.2

x = 6.8

Substitute x = 6.8 in y = 1.2x

y = 1.2 * 6.8

Evaluate

y = 8.2

Hence, the length is 6.8 meters and the width is 8.2 meters.

The area of the cross section of a sphere at the largest point is 100π square miles. what is the total surface area of this sphe

Firlakuza [10]

The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= $\pi\r^{2}$ Where r is the radius of the circle.

Given : $\pir^{2} = 100\pi$

Solving for r we have:

$r^{2} = \frac{100\pi }{\pi}= 100$

Or r= 10.

The area of a sphere is calculated by the formula :

$SA = 4\pi R^{2}$

Substituting r value we have:

SA= $4\pi\ 10 ^{2} = 400\pi$

The total surface area of this sphere is 400π .
