Question

The length and breadth of a rectangular park are 45.2 metres and 15 metres respectively. Calculate its area.

• A. 67.8 square metres
• B. 668.5 square metres
• C. 6580 square metres
• D. 678 square metres

Answer 1

The correct option is D

678 square metres

Area = length x breadth

Area = 45.2 x 15

First, mutiply 452 x 15 = 6780

Since there is one digit after the decimal point in 45.2 x 15, we put the decimal point after one place starting from the extreme right.

So, Area = 678.0 = 678 square metres
