Question

What is the perimeter of a rectangle having sides as 4 m and 6 m?

• A. 15 m
• B. 10 m
• C. 20 m
• D. 5 m

Answer 1

The correct option is C

20 m

Perimeter of a rectangle is 4 m + 6 m+ 4 m+ 6 m = 20 m

Alternatively, perimeter of a rectangle is given by an unchanging relation $2(l+b)$, where $l$ and $b$ are the length and breadth of the rectangle.

Hence, the perimeter
$=2(l+b)=2(4+6)=2\times 10=20m$
