Answer 1

Answer:

brain list & thanks please

Step-by-step explanation:

Length (l) of cardboard = 8.5 cm

Breadth (b) of cardboard = 5 cm

Area of cardboard including margin = l × b = 8.5 × 5 = 42.5 cm2

From the figure, it can be observed that the new length and breadth of the cardboard, when margin is not included, are 5 cm and 1.5 cm respectively.

Area of the cardboard not including the margin = 5 × 1.5 = 7.5 cm2

Area of the margin = Area of cardboard including the margin − Area of cardboard not

including the margin

= 42.5 − 7.5 = 35 cm2
