Rectangles ABCD and QRST are similar I 42 cm B 21 cm D (a) Determine the scale factor applied to rectangle ABCD to create rectangle QRST Show your work! 1 (b) Reproduce rectangle ABCD at a scale of Show your work and label measurements for each side of your rectangle.​

(a) Scale factor:

(b) See attachment

Step-by-step explanation:

Given

See attachment for ABCD and QRST

Solving (a): The scale factor of ABCD to QRST

This is calculated as:

Considering corresponding sides AB and QR

Make k the subject

Solving (b): Reproduce ABCD at scale factor of

The new rectangle will have the following side lengths.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
