Idk I’m not that very smart
Step-by-step explanation:

Area of rectangle = 408 in²
Length = 3x-2 and width = x
The area of a rectangle is given by :
A = lb
(3x-2)x = 408
x = 12 inch and x = -11.33 in
Neglecting negative value,
The width of rectangle = 12 inch
The length of rectangle = 3x-2 = 3(12)-2 = 34 inch

Base of triangle = 2x+2
Height = x
The area of a triangle is given by :

x = 24 cm and x = -25 cm
Neglecting negative value, x = 24 cm
Base = 2x+2 = 2(24)+2 = 50 cm
Hence, this is the required solution.
Answer:
Not very good at these but prob 1st and last
Step-by-step explanation:
Answer: B, 2.4 Units
Explanation: Since the two triangles are similar, the lengths of the triangles are equal in ratio. This equates to:
AB/DE = AC/DF
since the value of AB/DE IS 5/3, the ratio between AC and DF are the same.
Substitute the ratio with the values of AC and DF, and you will get the value of DF.
If you don't understand feel free to look at my workings
All the trianges involved are isosceles right triangles. You know that the hypotenuse is the leg multplied by √2.
ML = KM = KL/√2 = 2/√2
ML = KM = √2
