Question

find area of rectangle if lenght =2m30cm and breadth = 1m40mm.

Answer 1

Given length(l)=2m30cm
=2×100cm+30cm
=200cm+30cm
=230cm
Given breadth(b)=1m40mm
=100cm+4cm
=104cm

Area of the rectangle(A)=l×b
=230cm×104cm
=23920cm²
=23920/10000m²
=2.392m²

Answer 2

length= 2 m 30 cm = 230 cm

breadth= 1 m 40 mm = 1040 mm = 104 cm

area = length * breadth

        = 230 * 104 cm ^2

        = 23920 cm^2
