Solution

The correct option is A
$2 m$

Area of square $= 100 m^{2}$

Number of rectangles formed = 5

Area of each rectangle $= \frac{A r e a o f s q u a r e}{N u m b e r o f r e c t a n g l e s c r e a t e d} = \frac{100}{5} = 20 m^{2}$

length of rectangle = 10 m

breadth, b = ?

Area of rectangle = length x breadth

20 = 10 x b

$b = \frac{20}{10} = 2 m$

The breadth of the rectangle is 2 m
