Question

Darrell put 4 points on a grid and labelled them VV to YY, as shown on the diagram below.



Point VV is 56 millimetres from point XX.

Darrell adds a fifth point, ZZ so that the arrangement of points has one line of symmetry.

How far is point ZZ from point YY?

Worked Solution

VV to XX = 8 grid widths

⇒\rArr 1 width = 568\dfrac{56}{8} = 7 mm

∴\therefore Distance of ZZ to YY

= 4 × 7

= {{{correctAnswer0}}} {{{suffix0}}}

Answers

Specify one or more 'ANSWER' block(s) as exampled below.
Note: correctAnswer is required, the rest are optional. ("correctAnswer" is what the student would need to type in to the box to get the answer correct.)

For example:
correctAnswer: 123.40

And optionally, specify the following, but only if you need something different to the defaults: 'width' defaults to 5 if not present, and valid values are 3 to 10; 'prefix' and 'suffix' default to nothing if not present.
prefix: $
suffix: mm$^2$
width: 5
