Answer:

Step-by-step explanation:

a) Let's x the length of the side of the small square.

Thus,

x^{2}  + (\sqrt{40})^2 = (\sqrt{50})^2

x^{2}  + 40 = 50

x^{2}  = 50 - 40

x^{2}  = 10

x = \sqrt{10}

x=3.16

b) Now, the area of the small square is

A= x^{2}

A=(3.16)^2

A=9.99

Note that "gradient" means "slope" here.  The slope is -1 and the y-intercept is also -1.
