The equation is $b=\frac{2A}{h}$

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

Write the equation and circle the variable you want to make it subject
Keep it in one side and move all other in the other side
Make the coefficient of the subject 1

∵ A = $\frac{1}{2}$ × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ $\frac{2A}{h}= b$

- Switch the two sides

∴ $b=\frac{2A}{h}$

The equation is $b=\frac{2A}{h}$

Answer:

The length of Louise’s basement is 90 feet.

Step-by-step explanation:

Given:

Louis wants to carpet the rectangular floor of his basement.

The basement has an area of 4860 square feet.

The width of the basement is 3/5 it’s length.

Now, to find the length of Louise’s basement.

Let the length of basement be $x.$

So, the width is:

$\frac{3}{5}\ of\ x\\=\frac{3}{5}\times x\\=\frac{3x}{5}$

Area of the basement = 4860 square feet.

Now, to get the width of basement we put formula:

$Area=length\times width$

$4860=x\times \frac{3x}{5}$

$4860=\frac{3x^2}{5}$

Multiplying both sides by 5 we get:

$24300=3x^2$

Dividing both sides by 3 we get:

$8100=x^2$

Using square root on both sides we get:

$90=x$

$x=90\ feet.$

Therefore, the length of Louise’s basement is 90 feet.
