pls give me the full solution !!​

Answer 1

Answer:

make me brainlist

Step-by-step explanation:

breadth or width = x

 

length = 2x

 

(x)(2x) = 578

 

2x2 = 578

 

x2 = 289

 

x = 17

 

breadth = 17

 

length = 34

Answer 2

Answer:

Let breadth be x and length be 2x

We know that,

Area if rectangle=Length × Breadth

578=x × 2x

578=2x^2

578/2=x^2

289=x^2

x=289^2

x=17m

Breadth=17m

Length=17×2=34m

Perimeter=2(l+b)

=2(34+17)

=2(51)

=102
