Step-by-step explanation:

Length= 10cm, breadth= 8cm

Area = 80 cm2

As there is a margin of 1.5 cm

The length larger rectangle = length of smaller rectangle = 2 × 1.5 = 3

10 - 3 = 7 cm

the breath of small rectangles

8 - 3 = 5cm

Area of smaller rectangle = 7 × 5 = 35 cm2

Margin = 80 - 35 = 45cm2
