Answer:
The area would be doubled also 
The perimeter will be increased in a factor of 1.4
Step-by-step explanation:
Originally the area of new crate = L * B = 1.2 * 0.8 = 0.96 m^2
perimeter is 2(L+ B) = 2(1.2 + 0.8) = 4 m
Now let’s double the width , it becomes 0.8 * 2 = 1.6 m
Area would be 1.6 * 1.2 = 1.92 m^2 which is two times the previous area 
The increased perimeter will be 2(1.6 + 1.2) = 5.6 m
This is an increase in factor of 1.4

Answer:
9/4
Step-by-step explanation:
This is quite simple you do 1/2 divided by 2/8 which will become multiplication. Then its that number plus 1/4
you get a answer of 
9/4 in fraction form
2.25 in decimal form 
2 1/4 in mixed fraction form

Answer
Find out the value of x .
To proof
SAS congurence property
In this property two sides and one angle of the two triangles are equal.
in the Δ ADC and ΔBDC
(1) CD = CD (common side of both the triangle)
(2) ∠CDA = ∠ CDB = 90 ° 
( ∠CDA +∠ CDB = 180 ° (Linear pair)
as given in the diagram
 ∠CDA  = 90°
∠ CDB = 180 ° - 90°
∠ CDB = 90°)
(3) AD = DB (as shown in the diagram)
Δ ADC ≅ ΔBDC
by using the SAS congurence property .
AC = BC 
(Corresponding sides of the congurent triangle)
As given 
 the length of AC is 2x and the length of BC is 3x - 5 .
2x = 3x - 5
3x -2x =5
x = 5
The value of x is 5 .
Hence proved
