Question

what is the dimension of a rectangle of length and breadth of 1m40cm

Answer 1

Area of rectangle= length×bredth

so,

Length = 1m = 100Cm

Breadth= 40Cm

therefore,

$100 \times 40 = 400$

Answer 2

Area of rectangle = length * breadth
Length = 1 metre :- 100cm
Breadth= 40cm
Area of rectangle = 100*40
Area of rectangle = 4000
