Corey has a garden in the shape of a square. The garden covers 64 square feet. What are the possible dimensions?
Valentin [98]

Answer:

64 = 1 x 64, 2 x 32, 4 x 16, or 8 x 8.

Step-by-step explanation:

If a garden covers 64 square feet <em>total, </em>then you simply find the common factors of 64.

64: 1, 2, 4, 8, 16, 32, 64.

So, the possible dimensions are,

64 = <u>1 x 64, 2 x 32, 4 x 16, or 8 x 8</u>

Square feet total is 64. So put 4x16 or 8x8 or 2x32. Because if you multiply lets say 4x16, that would equal 64 square feet total.

If you were to multiply 64x64 that would be 4,096 square feet. and that would be a BIG NO NO!!!

A wall with a height of 20 feet is braced with a support post that forms a 30 degree angle with the top of the wall. What is the
dexar [7]

The length of the support post is 40 ft.

<u>Solution:</u>

Given, the height of the wall is 20 ft; support post forms 30 degree

Refer the attached image

Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and \angle A is 30 degree (\theta) and AC is the length of the post.

To find: The length of the post (AC)

we know the formula, sin\theta=\frac{opp}{hyp} (trigonometric formula)

On substituting the values we get,

\Rightarrow sin(30^{\circ})=\frac{20}{AC}

The value of sin 30 degree is 0.5

\Rightarrow 0.5=\frac{20}{AC}\rightarrow AC=\frac{20}{0.5}\rightarrow AC=40 ft
