Given:
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
To Find:
The length of qr ,sr and the two diagonals pr and qs.
Solution:
Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm
Answer:
QR = 5 cm
SR = 12 cm
PR = 13 cm
QS = 13 cm
