The sides of a square are 4 2/9

I'm going to assume you want to find the area and perimeter.

Note that the sides of a square are always the same.

Find the area [ A = bh ]

A = 4 2/9 * 4 2/9

A = 17 67/81

Find the perimeter [ P = 2b + 2h ]

P = 2(4 2/9) + 2(4 2/9)

P = 16 8/9

Therefore, the area is 17 67/81 and the perimeter is 16 8/9

Best of Luck!

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
