A rectangular lawn has an area of 1815 square yards. If its length is 50 metres, find its width in metres, given that 1 metre equals 1.1 yards.
Worked solution (try it first)
Change the length to yards to match the area:
50×1.1=55 yards.
Width
= area
÷ length
=1815÷55=33 yards.
Change back to metres:
33÷1.1=30 m, option D.
