Rectangle:
P = 2 (L+W) but length is 2 meters longer than wide
then L = W + 2, So
P = 2 (L + W)
24 = 2(W+2+W)
24 = 2 (2 + 2W)
24 = 4 + 4W
So 4W = 24 -4 =20
W = 20/4= 5, L = 5+2= 7

Double check
24 = 2*(5+7) = 2 *12 = 24

Answer:

the width of the rectangle is, 5 meters

Step-by-step explanation:

Perimeter(P) of the rectangle is given by:

P = 2(l+w)                  ....[1]

where,

l is the length and w is the width of the rectangle.

As per the statement:

Tracy needs to find the length and width of the equipment storage room where she works.

The room is 2 meters long than it is wide. its perimeter is 24 meters.

then;

l = w+2

P = 24 meter

Substitute the given values in [1] we have;

24 = 2(w+2+w)

Divide both sides by 2 we have;

12 = 2w+2

Subtract 2 from both sides we have;

10 = 2w

Divide both sides by 2 we have;

5 = w

or

w = 5 meters

Therefore, the width of the rectangle is, 5 meters

4. State what additional information is required in order to know that the triangles are congruent by the SSS Triangle Congruenc
d1i1m1o1n [39]

The additional information required to prove the SSS Triangle Congruence Postulate is BC = KC

<h3>How to state the additional information required?</h3>

The congruence postulate is given as:

SSS Triangle Congruence Postulate

The above means that the three sides of the triangles are congruent.

From the figure, the following side lengths are said to be congruent

AK and AB

AC and AC

For the congruence postulate of the triangle to be SSS Triangle Congruence Postulate, then the third corresponding sides must be congruent

This is represented as:

BC = KC

Hence, the additional information required to prove the SSS Triangle Congruence Postulate is BC = KC
