If the ratio of the width to the length is 1 : 2 then, we can represent their respective lengths using x and 2x.
Width = x
Length = 2x
2(x) + 2(2x) = 324
2x + 4x = 324
6x = 324
x = 54
2x = 108
The width is 54 ft. and the length is 108 feet. Hope this helps!
In an equation using x is just a place holder because those numbers are variables so it doesn't matter whether it is x or w.
Answer:
i think its c
Step-by-step explanation:
We are given the two bases of the trapezium:

The formula for the area of the trapezium is

So, we only need to figure out the length of the height EF.
We know that FA+EF = 11. Also, we're given that the perimeter of ABCF is 28, which means

So, we can deduce

And so we're ready to use the solving formula:
