Answer:
The first thing we need to do is find the area of the rectangle...
l x w = A
7 x 8 = 56
So the area of the first rectangle is 56m.
Now we multiply each dimension by 5...
8 x 5 = 40
7 x 5 = 35
So, now the width is 40m and the length is 35m,
Then, find the area of the new rectangle...
35 x 40 = 1400
The area of this rectangle is 1,400m!
1,400 / 56 = 25
So, by multiplying each dimension by 5, the area is now multiplied by 25!
