Column A	Column B
Area of a figure	$252\,\mathrm{m}^2$

Solution:

Concept:

The area of the given figure is the sum of a semicircle and a rectangle.

Explanation:

The rectangle has length

14\,\mathrm{m}

and breadth

7\,\mathrm{m}

So, rectangle area

=14 \times 7=98\,\mathrm{m}^2

The semicircle has radius

r=7\,\mathrm{m}

Area of semicircle

=\frac{1}{2}\pi r^2=\frac{1}{2}\times\frac{22}{7}\times7^2=77\,\mathrm{m}^2

Total area

=98+77=175\,\mathrm{m}^2

Column A

=175\,\mathrm{m}^2

and Column B

=252\,\mathrm{m}^2

Since

252>175

, Column B is greater.

Answer:

Column B is greater, so option B is correct.
