Find the Perimeters of the rectangle whale<br>degonal is 5cm and lenght is 4cm ​
amid [387]

Answer:

14

Step-by-step explanation:

First, we have to get the breadth value.

By the pythagoras theoreom,

Diagonal²=length² + breadth²

breadth = √( Diagonal²- length²)

breadth = √( 5² - 4²)

breadth = √9

breadth= 3

Perimeter of a rectangle = 2x ( length + breadth)

                                         = 2 x (  4 + 3)

                                         = 2 x 7

                                         = 14
