Answer:

Cuadrilátero A: A = y^{2}+4\cdot y +4

Cuadrilátero B: A = a^{2}+6\cdot a + 9

Step-by-step explanation:

Existen dos formas distintas de determinar las áreas de cada cuadrilátero:

(i) <em>Obtener el área de cada cuadrado y sumar los resultados.</em>

(ii) <em>Calcular los lados del cuadrilátero grande y determinar el área. </em>

Cuadrilátero A

Método (i)

A = y^{2}+2\cdot y +4+2\cdot y

A = y^{2}+4\cdot y +4

Método (ii)

A = (y+2)\cdot (y+2)

A = y^{2}+4\cdot y + 4

Cuadrilátero B

Método (i)

A = a^{2}+3\cdot a +9 + 3\cdot a

A = a^{2}+6\cdot a +9

Método (ii)

A = (a+3)\cdot (a+3)

A = a^{2}+6\cdot a + 9

The slope is 1, so m = 1. 
The given point is (x,y) = (1,5) which means x = 1 and y = 5 pair up together.

Plug the three pieces of info (m = 1, x = 1, y = 5) into the y = mx+b equation. Then solve for b

y = mx+b
y = 1*x + b ... replaced m with 1
5 = 1*1 + b .... replaced x with 1, replaced y with 5
5 = 1+b
1+b = 5
b+1 = 5
b+1-1 = 5-1
b = 4

Since m = 1 and b = 4, we know that y = mx+b turns into y = 1x+4 which simplifies to y = x+4
