Answer:

The answer to your question is B = B (3, -7)

Step-by-step explanation:

Data

A = (-6, 5)

M = (-1.5, -1)

Process

1.- Write the formula of Midpoint

Xm = (x1 + x2)/2

Ym = (y1 + y2)/2

2.- Solve for x2 and y2

x2 = 2Xm - x1

y2 = 2Ym - y1

x1 = -6 y1 = 5 Xm = -1.5 Ym = -1

3.- Substitution

x2 = 2(-1.5) + 6

y2 = 2(-1) - 5

4.- Simplification

x2 = -3 + 6

y2 = -2 - 5

5.- Result

x2 = 3

y2 = -7

B (3, -7)

$\text{Let the side of square 1, square 2 and square 3 be x, y and z respectively.}\\\\\text{Given that,}\\\\\text{Perimeter of square 1,~~ p =100 units.}\\\\\text{So}~ x=\dfrac p 4 = \dfrac{100}4 =25~\text{units.}\\\\\\\text{Area of square 2, a = 225 units}^2\\\\\text{So}~y = \sqrt{a} = \sqrt {225} = 15~ \text{units.}\\\\\text{Use Pythagorean theorem to find z}^2\\\\x^2 =y^2 +z^2 \\\\\implies 25^2 = 15^2 +z^2\\\\\implies z^2 = 625 - 225 = 400\\\\\\$
