The perimeter of a rectangle is 52 m. If the width were doubled and the length were increased by 17 m, the perimeter would be 96
1 answer:
Let be the dimensions of the rectangle. If the original perimeter is 52, we deduce that
Doubling the width and increasing the length by 17 leads to a new perimeter of
From the first equation, we know that (for example)
Plug this in the second equation to get
So, the original length was 21, which implies that the original width was

Answer:
Step-by-step explanation:
Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are of these parts in total. Because each of these parts make up
of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.
The top left and bottom right both have one part shaded each for a total of parts.
The top right and bottom left have and
parts shaded, respectively, for a total of
parts.
Therefore, in total, there are parts shaded out of
total parts.
Thus, the percentage of the total area that is shaded is:
