Answer:
Step-by-step explanation:
Given are two rectangles MNOL and IJKH
MNOL is the image and IJKH is the preimage.
OBviously similarity is preserved between these.
Hence sides will be proportional
i.e. l1/l2 = w1/w2 = Scale factor k
This can also be written as
Scale factor square = 
Scale factor = square root of ratio of rectangle areas
Find ratio as

k = Scale factor = square root of the above fraction
=
39.95 + 9.80 = 49.75
70.23 - 49.75 = 20.48
20.48 / 0.32 = 64
The truck was driven 64 miles.
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
I think this might be the answer since (a+b) equals 4, and ab= 3. I'm not sure.
a3 + b3
= (4)3+4(3)
= 12+12
= 24
