Square E has side lengths of e cm Square F has side lengths of f cm
The area of square E is 69% greater than the are of square F
work out the ratio of e:f

The length ratio of square E to square F is 1.3.

Step-by-step explanation:

The area of the square is equal to the square of its side length. The ratio of areas of square E to square F is:

(1)

Where:

, - Lengths of squares E and F, measured in centimeters.

Then, the length ratio of square E to square F is:

The length ratio of square E to square F is 1.3.

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
