Please help me with the following (1-5) Write the following numbers in scientific notation.

1. 405 352 cm =

2. 7.6352 x 10-3 kg =

3. 3.1 x 104 mm + 4.87 x 105 mm =

4. (4.8 x 105 km) x (2.0 x 103 km) =

5. (3.3 x 10-4 mL) ÷ (1.1 x 10-6 mL) =

we need the options

step-by-step explanation:

what do u need to know

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
