juin [17]

Given:

The perimeter of a rectangular building is 1200 feet.

The width of the building is 2 feet less than three times the length.

To find:

Width of the building.

Solution:

Let length of the building be x.

Then, width = 3x-2

We know that,

Perimeter=2(length +width)

1200=2(x+3x-2)

1200=2(4x-2)

1200=8x-4

Add 4 on both sides

1204=8x

Divide both sides by 8.

\dfrac{1204}{8}=x

150.5=x

Now,

Width=3x-2

Width=3(150.5)-2

Width=451.5-2

Width=449.5

Therefore, the  width of the building is 449.5 feet.

Paladinen [302]

Answer:

Step-by-step explanation:

Given:

ΔCAD and ΔCBD

∠A ≅∠B (Angle)

AD ≅BD (Side)

From the graph we see that

CD≅CD (Side)

because of reflexive propriety ( a line segment is congruent with itself)

If you put in order those congruencies we have SSA witch does NOT prove congruence.

we not use SAS because the angle between the sides is not congruent
