A rectangular picture frame has side lengths of 12 in by 9.5 in what is the length of the diagonal of the picture

Length of diagonal of picture = 15.30 inches

Step-by-step explanation:

Given that:

Side lengths of picture frame = 12 inches by 9.5 inches

As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.

Using Pythagorean theorem;

a²+b²=c²

Putting the values in the theorem

Taking square root on both sides

Hence,

Length of diagonal of picture = 15.30 inches

Step-by-step explanation:

formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side

use this formula to find the Area
