Tristan is working on dilating rectangles. Rectangle ABCD is dilated by a factor of 3. The resulting rectangle WXYZ has an area of 72 cm². Tristan found that the area of rectangle ABCD must be 8 cm². Is he correct?

No, because he needs to divide the area of rectangle WXYZ by 3.

No, because he needs to multiply the area of rectangle WXYZ by 3.

Yes, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.

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 )
