Question

If a square of side 1.5 m is cut out from
a square plastic sheet of side 3 m, find
the area of the remaining sheet.

Answer 1

initial area of the plastic sheet = 3 × 3 = 9m²

area of the square cut out = 1.5 × 1.5 = 2.25m²

area of the plastic sheet after cutting out of the square = 9 - 2.25 = 6.75m²
