Answer
a). 91.4 m by 48.8 m,
b). 27.9 cm by 28.6 cm.
Work Step by Step
a). 1 feet = 0.3048 m
So, 300 feet = $300\times 0.3048$=91.44=91.4 m (rounded off)
and 160 feet = $160\times 0.3048$=48.768=48.8 m (rounded off)
b). 1 inch = 2.54 cm
So, 11 inch = $11 \times 2.54 $ = 27.94 cm = 27.9 cm (rounded off)
Similarly, 11$\frac{1}{4}$ inch = $\frac{45}{4}\times2.54$=28.6 cm (rounded off).
