The perimeter of an ICU ward, that is rectangular in shape, is 258 feet. The width is 37 feet less than the length. Find the dim
zubka84 [21]

The dimensions of the rectangle is 83 feet x 46 feet

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P = 2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P = 2 ( Length + Width )

Given data ,

The perimeter P of the rectangle = 258 feet

Let the length of the rectangle be = L

Let the width of the rectangle be = W

And , The width is 37 feet less than the length. ,

So , W = L - 37

Perimeter P = 2 ( Length + Width )

Substituting the values of L and W in the equation , we get

Perimeter P = 2 ( L + L - 37 )

2 ( L + L - 37 ) = 258

( L + L - 37 ) = 129

2L - 37 = 129

Adding 37 on both sides , we get

2L = 166

Divide by 2 on both sides , we get

Length L of the rectangle = 83 feet

Substituting the value of L in equation ,we get

W = L - 37

Width W of the rectangle = 46 feet

Therefore , Length = 83 feet and Width = 46 feet

Hence , the dimensions of the rectangle is 83 feet x 46 feet

What is -2 and 2 fifths squared?<br><br> Thanks!
Luba_88 [7]

Answer:

\frac{144}{25}

Step-by-step explanation:

We begin with (-2 \frac{2}{5} )^2

First, lets turn this mixed number into an improper fraction/

-2 \frac{2}{5} =-\frac{12}{5}

Now that we have this, we can square it and then simplify it.

(-\frac{12}{5} )^2 =\frac{12^2}{5^2} *(-1)^2=\frac{144}{25} *1=\frac{144}{25}
