Find the value of y in rectangle QRST.

11y+9

19y+28

20y

The value of y in rectangle QRST is 1

Step-by-step explanation:

A Rectangle is a quadrilateral with opposite sides equal and parallels among several of its other features. Its other features include opposite ends meet at right angle and diagonals are equal

In the given data the sides are "11y+9" "19y+28" and "20y"

Since for rectangle opposite sides are equal

hence 11y+9 must be equal to 20y

11y+9=20y - - equation 1

rearranging the equation we get,

9y=9 (transferring 11y to the right side of the equation)

Therefore y=1

Hence y=1 in the given rectangle QRST
