Points m is the midpoint of FG. Can you determine the value of a?
GenaCL600 [577]

Using the midpoint concept, it is found that the value of a is of a = 2.

<h3>What are the coordinates of the points?</h3>

Researching this problem on a search engine, the coordinates are given as follows:

  • F(b + 1, a + 2).
  • M(3,5).
  • (2a, 3b+3).

<h3>What is the midpoint concept?</h3>

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

Hence the following system of equations can be built:

(b + 1 + 2a)/2 = 3.

b + 1 + 2a = 6.

b = 5 - 2a.

(a + 2 + 3b + 3)/2 = 5

a + 3b + 5 = 10

a + 3b = 5.

Since b = 5 - 2a, we have that:

a + 15 - 6a = 5.

5a = 10

a = 10/5

a = 2.

The value of a is of a = 2.

Given square ABCD, with point P on side AB , point Q on side BC, point R on side CD, and point S on side DA as shown. Additional
sveta [45]

The ratio of the area of square PQRS to the area of square ABCD is 5/9

<h3>Area of square ABCD</h3>

Assume the measure of the side lengths of the square ABCD is 1, then the area of the square ABCD is:

A_1 = 1 \times 1

A_1 = 1

See attachment for the diagram that represents the relationship between both squares.

<h3 /><h3>Pythagoras theorem</h3>

The measure of length PQ is then calculated using the following Pythagoras theorem:

PQ^2 = (\frac 13)^2 + (\frac 23)^2

Evaluate the squares

PQ^2 =\frac 19 + \frac 49

Add the fractions

PQ^2 =\frac 59

<h3>Area of square PQRS</h3>

The above represents the area of the square PQRS.

i.e.

A_2 =\frac 59

So, the ratio of the area of PQRS to ABCD is:

Ratio = \frac{A_2}{A_1}

This gives

Ratio = \frac{5/9}{1}

Ratio = \frac{5}{9}

Hence, the ratio of the area of square PQRS to the area of square ABCD is 5/9
