Question

Figure A is a scale image of figure B. What is the value of x?

Answer 1

The value of x = 20.

Explanation:

Figure B is the scale image of A.

It is clear that:

• side 10 of figure A has the image side of 12.5 in figure B.

which can be obtained by multiplying 10 with 1.25

i.e.

• 10*1.25=12.5

so the side 16 of figure A must have to be multiplied by 1.25 to get the image the figure B.

so

• 16*1.25=20

Therefore, the value of x = 20.
