if your in a rush I'll explain later
1. 5/11
2. 11
3. 2
These are all just properties of logarithms.

Substitue 2x for y in the second equation:

Rearrange to

form:

Factor:

Zeros are

and

To find y-coordinates of pts of intersection, plug these x-values into first equation to get

and
Answer:
30,340 all you gotta do is add the 2 numbers together
Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
