Figure A is a scale image of Figure B Figure A maps to figure B with scale factor of 0.8 PLEASE HELP ME!!

X=4

Scale figure tells you how much bigger or smaller an object is compared to another. Having a number greater than 1 makes the object bigger, while any scale factor below 1 makes the object smaller.

In this case we are given 2 rectangles that are similar, therefore can map onto each other with a scale factor. So we need to use the given scale factor and multiply it by the side (or other things in different cases, such as area).

What we first want to do is find out what our scale factor is, which can be found in the question and is 0.8. Now we need to know what this scale factor is for, which is going from figure A to B, therefore we multiply the side given in figure A by the scale factor, which is 5. 5*0.8= 4. 4 would then be your new side on figure B that is similar to figure A.
