Answer»

ANSWER:

Perimeter of the trapezium = 10 11/30 cm

Perimeter of the square = 11 cm

The Perimeter of the square is the greatest perimeter

Step-by-step EXPLANATION:

(i) AD = BC = 1 3/5 cm = 8/5 cm

EH = AB = 2 3/4 cm = 11/4 cm

DC = DE + EH + HC = 5/6 + 11/4 + 5/6

= 10/12 + 33/12 + 10/12

= 53/12 cm

Perimeter = AB + BC + CD + DA

= 11/4 + 8/5 + 53/12 + 8/5

= 165/60 + 96/60 + 265/60 + 96/60

= 622/60

= 311/30 cm

= 10 11/30

(ii) a = 2 3/4 cm = 11/4 cm

Perimeter of the square = 4a units

= 4 × 11/4

= 11 cm

The Perimeter of the square is the greatest perimeter
