plz give answer fast.................​

Answer 1

Answer:

let the length be x and breath ne 2x

Step-by-step explanation:

240=2x+x

240=3x

x=240÷3

×=80

Answer 2

Answer:

b= x. l= 2x -(1)

2(l+b)= 240

l+b= 120

from -(1)

2x+x= 120

3x= 120

x=40

hence, b= 40 and l= 80

now in a rectangle all angles are 90 and diagonal bisect the angle hence angle is 45.

now 40÷x= cos 45

40÷x= 1÷√2

now x= 40 √2

hence diagonal 40 √2
