A real estate purveyor purchases a 60{,}00060,00060, comma, 000 square foot \left(\text{ft}^2\right)(ft 2 )(, start text, f, t,
finlep [7]

Answer:

200 feet

Step-by-step explanation:

Area of the warehouse =60,000$ ft^2

Let the length of the warehouse=l

The warehouse's width is exactly  \dfrac23 of its length

Therefore: Width of the warehouse=\dfrac23l

Area =Length X Width

Therefore:

\dfrac23l*l=60000\\$Cross multiply\\2l^2=60000*3\\2l^2=180000\\$Divide both sides by 2\\2l^2 \div 2=180000 \div 2\\l^2=90000\\l^2=300^2\\$Length, l=300 feet\\Recall: Width =\dfrac23l\\$Therefore, Width of the warehouse=\dfrac23*300=200$ feet

What Is The Length Of Side BD?
emmainna [20.7K]
This is a rectangle, meaning that all angles are right angles and all sides opposite to one another have equal length.

Since the length of CD is 24, the length of AB must also be 24.
Angle B is a right angle because this is a rectangle.

See anything? I'll you a hint. We have a right triangle with only one missing value.

What do we use to solve for missing lengths in a right triangle? The Pythagorean theorem, of course!

a^2+b^2=c^2

The length of c (the hypotenuse) is 26.
The length of a (one leg) is 24.
The length of b is unknown and we want to find it.

24^2+b^2=26^2

576+b^2=676

Subtract 576 by both sides.

b^2=100

Take square root of both sides.

b=10

The length of the missing leg is 10, meaning that the length of BD is 10.

This is what you should be needing. Enjoy!

Sandra has 46 fewer coins than Martha. Sandra has 57 coins . how many coins does Martha have?
hoa [83]
M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)

M=103

So martha has 103 coins!
