Hello, can someone help me with this problem?
exis [7]

Answer:

Area of Rectangle A

Area = 4x^2

Area of Rectangle B

Area = 2x^2

Fraction

Fraction =\frac{2}{3}

Step-by-step explanation:

From the attached, we understand that:

The dimension of rectangle A is 2x by 2x

The dimension of rectangle B is x by 2x

Area of rectangle is calculated as thus;

Area = Length * Breadth

Area of Rectangle A

Area = 2x * 2x

Area = 4x^2

Area of Rectangle B

Area = x * 2x

Area = 2x^2

Area of Big Rectangle

The largest rectangle is formed by merging the two rectangles together;

The dimension are 3x by 2x

The Area is as follows

Area = 2x * 3x

Area = 6x^2

The fraction of rectangle A in relation to the largest rectangle is calculated by dividing area of rectangle A by area of the largest rectangle;

Fraction = \frac{Rectangle\ A}{Biggest}

Fraction =\frac{4x^2}{6x^2}

Simplify

Fraction =\frac{2x^2 * 2}{2x^2 * 3}

Fraction =\frac{2}{3}

A person who is 6ft tall walks away from a streetlight. When the person is 15 feet away from the light, the tip of his shadow is
Citrus2011 [14]
We essentially have a ratio here:
\frac{shadow}{actual}

Since we know the ratio is going to stay constant at \frac{5}{6}, we can use this to find the height of the lamp along with the information that the total distance from the lamp to the tip of his shadow is 20:
\frac{5}{6}=\frac{20}{h}
5h=120
h=24
