Question

the pair of adjecent sides of recyangle are in the ratio 5:12.if the length of the diagnol is 26 cm find the length of the sides and perimeter​

Answer 1

Answer:

sides=24*10 cm

perimeter=68 cm

Step-by-step explanation:

let the side=x

therefore,    (5x)^2 + (12x)^2= (26)^2               (using pythagoras rule)

                     25x^2+144x^2= 676

                      169x^2           = 676

                            x^2           = 676/169

 this implies,              x        = 26/13= 2cm

                    therefore, length= 2*12= 24cm

                                      breadth=2*5= 10 cm

Perimeter = 2(l+b) = 2(24+10) = 2*34 = 68 cm.
