If a width of a rectangle is 5 1/6 cm and its length is 2 2/7 cm what is its area?

azamat

Answer:

11.8095238095 or 11.81

Step-by-step explanation:

The way to figure out the area of a rectangle is by multiplying the width by the length. In your case, you would multiply 5 1/6 by 2 2/7 to get 11.8095238095 but we can always round it to 11.81. I hope this helps...

[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 45°

Adjacent Leg = 25

Hypotenuse = x

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(45^\circ) = \frac{x}{25}$
[Multiplication Property of Equality] Multiply 25 on both sides: $\displaystyle 25cos(45^\circ) = x$
Rewrite: $\displaystyle x = 25cos(45^\circ)$
Evaluate: $\displaystyle x = \frac{25\sqrt{2}}{2}$
