Arectangle has an original area of 50 square feet. a similar rectangle has the new area of 1,250 square feet. what is the scale factor for the similar rectangles?

Hey there.

To find the scale factor between these two rectangles, we need to divide our new by our original.

Our new area = 1,250 sq ft
Our old area = 50 sq ft

1250 / 50 = 25.

This means our scale factor is 25.

I hope this helps!

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
