Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
just make the sides of the rectangle 2 and 3, the area is 6 that means that the perimeter is 10 (2+3+2+3) the perimeter of the square is 10 also so each side is 10/4 the area of the square is 10/4*10/4=100/16=25/4 so the ratio of area of R to S is 6 / 25/4 or 24/25
Rectangular's sides are 2, 3, 2, 3, therefore perimeter is 10 If the square has the same perimeter - 10 - that means that the lengh of one side is 2,5 Area of rectangular is 2*3=6 Area of square 2,5*2,5=6,25 Although we do not have answer choice for that, and we need integers in ratio, therefore we multiply both areas by 4 and get 24:25
