The rectangle has sides with a length 16 and 12. The length of the diagonal of a rectangle with sides a and b is given by sqrt(a^2 + b^2).

Substituting the values given , the length of the diagonal is sqrt(16^2 + 12^2)

=> sqrt (256 + 144)

=> sqrt...

The rectangle has sides with a length 16 and 12. The length of the diagonal of a rectangle with sides a and b is given by sqrt(a^2 + b^2).

Substituting the values given , the length of the diagonal is sqrt(16^2 + 12^2)

=> sqrt (256 + 144)

=> sqrt 400

=> 20

The perimeter of the triangle made with the sides and the diagonal is 20 + 12 + 16 = 48

**The perimeter of the triangle is 48.**
