Question

Find the area of this rectangle in
i) cm2
ii) mm2
19mm
2.3cm

Answer 1

i) 2.3 cm » 2.3*2.3=4.9 cm2

ii) 19 mm » 19.19=361 cm2

Answer 2

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
