Answer 2

Answer:

Step-by-step explanation:

In a rectangle, each angle measures 90°.

Therefore PSR is right angled at S

Using Pythagoras theorem, we get

 

⇒ PS2 + SR2 = PR2

⇒ PS2 + 1502 = 1702

⇒ PS2 = 1702 – 1502

⇒ PS2 = 6400

⇒ PS = √6400

⇒ PS = 80

Therefore perimeter of the rectangle PQRS = 2 (length + width)

= 2 (150 + 80) m

= 2 (230) m

= 460 m
