Why did the dog jump into the pool?
because he was a hot dog !
To find the area of a rectangle the formula is length times width
rectangle A = l x w
= 24 x 20
= 480
480 is the area of rectangle A
rectangle B's width is 12 meters less than rectangle A
since the width of rectangle A is 20 you take 20 and subtract 12
20 - 12 = 8
the width of rectangle B is 8
now since the question said that rectangle A and B both have the same area you put 480 into the formula
and since we now have the width of rectangle B we can figure out the length
Area = l x w
480 = length x 8
480 divided by 8 is 60
60 is rectangle B's length
so the answer is b)
