Find the area of this rectangle in

i) cm2

ii) mm2

19mm

2.3cm

Step-by-step explanation:

i) Length = 2.3 cm

Width = 19 mm = 19/10 = 1.9cm {10mm = 1 cm}

Area of rectangle = length * width

= 2.3*1.9

= 4.37 cm²

ii) Length = 2.3 cm = 2.3*10 = 23 mm

Width = 19mm

Area of rectangle = length * width

= 23 * 19

= 437 mm²

i) 2.3 cm " 2.3*2.3=4.9 cm2

ii) 19 mm " 19.19=361 cm2
