It forms two rectangle.
The area of largest rectangle ( The whole sheet) = 11×8 = 88 cm²
The length of the margin = 1.5
therefore length of the small rectangle = 11 -(2×1.5)= 9 (because margin cut both sides of the sheet)
breadth = 8 -(2×1.5)= 5
Area of small rectangle = 9 × 5 =45 cm²
Therefore area of margin = (Area of big rectangle - small rectangle)
= 88 -45 = 43 cm²
I hope my answer is helpful to u.
