Question

A rectangular airstrip measures 32.30 m by 210 m, with the width measured more accurately than the length. Find the area, taking into account significant figures. (a) 6.783 0 x 10^3 m^2 (b) 6.783 x 10^3 m^2 (c) 6.78 x 10^3 m^2 (d) 6.8 x 10^3 m^2 (e) 7 x 10^3 m^2

Answer 1

Answer: (d). Area = 6.8 × 10^3 m^2 (to 2 significant figure)

Step-by-step explanation:

The area to find rectangular is:

Area = length × breadth

Area = 32.30 × 210

Area = 6783 m^2

Area = 6.8 × 10^3 m^2 (to 2 significant figure)
