Answer:

the diagonal measurement from corner A to corner B=15 inches

Step-by-step explanation:

as we know that the loptop has the shape of a rectangle that means all it's angles are right angles. so we can use the pythogoras theorem to find out the diagonal of the rectangle.

let us denote the diagonal of rectangle by D and the sides of rectangle be denoted by X=12 and Y=9

so by using pythogoras theorem we have,

D^{2} =X^{2} +Y^{2}

D^{2}=225

D=15

Hence the diagonal measurement from corner A to corner B is 15 inches.

Answer:

The diagonal measures 15 inches

Step-by-step explanation:

The diagonal of the Marcy's rectangular laptop forms a right angle triangle with its width and length.


We can use the Pythagoras Theorem to write the following equation,

|AB|^2=12^2+9^2


This implies that,

|AB|^2=144+81


We simplify the right hand side to obtain,

|AB|^2=225


We take the positive square root of both sides to obtain,


|AB|=\sqrt{225}


|AB|=15inches


Hence the diagonal of Marcy's laptop measures 15 inches.
