Answer:
5/18 in²
Step-by-step explanation:
The area of a rectangle is found by multiplying its length by its width. For dimensions of 5/6 in by 1/3 in, the area is ...
(5/6 in)·(1/3 in) = 5/18 in²
Answer:
5) 1.5 : 7
Step-by-step explanation:
I think for 4) you need only one ratio, for example
The ratio of lemon to sugar is
1 : 1,5

Answer:

Step-by-step explanation:
Let A1 be the area of one square and A2 be the area of second square
So,
A1 = s^2
where s is side of square

So side of one square is 
To calculate the length of fence we need to find the perimeter of the square
So,
P1 = 4 * s

For second square:

The perimeter will be:

So the total fence will be: P1+P2
