A rectangular lawn has an area of 1815 square yards. if its length is 50 meters, find its width in meters given that 1 metre equals 1.1 yards
39.93
35.00
33.00
30.00
Spiegazione
1m = 1.1 yard, length(L)= 50m
= (50 x 1.1)yards
= 55 yards
Area(A) = length(L) y width (W)
1815 = 55y width (W)
width (w) = \(\frac{1815}{55}\)
= 33 yards
But 33 yards = 30 meters
