Answer:
The actual width of the school yard is 66 m.
Step-by-step explanation:
Given,
Width of yard in drawing = 11 mm
We have to find the actual width of the school yard.
Solution,
The scale used by Belle is;
[tex]1\ mm=6\ m[/tex]
Where, 'mm' stands for 'millimeters' and, 'm' stands for 'meters'.
To find out the actual width of the school yard, we use the unitary method.
According to this, we will multiply drawing width of the yard by 6 m.
[tex]Since\ 1\ mm=6\ m\\\\\therefore\ 11\ mm=6\times11=66\ m[/tex]
Hence The actual width of the school yard is 66 m.
