This is a similar triangles problem:

h/s=H/S

In this case:

p/(2yd(36in/yd))=(5(12)+6)/(2ft(12in/ft))

p/72=66/24, now multiply both sides by 72

p=72(66/24)

p=4752/24

p=198 inches

Answer:

option C is correct

Height of the pole is, 198 inches

Step-by-step explanation:

Given: Height of boy = 5ft 6 in , shadow of boy = 2ft

To find the height of pole if it casts a shadow 2 yards long.

Using conversion:

1 yards = 36 inches

1 ft = 12 inches.

Then;

5ft 6 in = 66 inches

2 ft = 24 inches.

2 yards = 72 inches.

Now, using proportions to find the height of pole.

Let height of pole is, h

Proportion says that two ratios are equal.

then;

\frac{height of boy }{Shadow of boy} = \frac{Height of pole }{Shadow of pole}

Substitute the values:

height of boy = 66 inches  ,            height of pole = h

Shadow of boy = 24 inches  and    shadow of pole = 72 inches

⇒  \frac{66}{24} = \frac{h}{72}

Multiply both sides by 72 we get;

h = \frac{66}{24} \times 72

or

h = 66 \times 3 = 198 inches

therefore, the height of the pole is, 198 inches

What is this factored?
Mandarinka [93]
The factored form of an equation is the simplest form of the equation that is obtained by factoring out a common variable or constant from multiple terms. Many types of polynomials are presentable in factored form, but the more terms an equation contains, the more difficult it is to find common factors.
