(SAT Prep) What is the sum of lengths of the two diagonals in a rectangle 5 by 12?

Step-by-step explanation:

To find the length of the diagonal, use Pythagorean theorem.

(diagonal)² = (length)² +(width)²

                  = 12² + 5²      

                  = 144+ 25

                 = 169

diagonal = √ 169 = 13 units

Sum of lengths of two diagonals = 13 + 13 = 26 units

In rectangle, diagonals are of equal length.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
