a) 45 cm; b) 0.25 m; c) 650 mm; d) 3 m by 9 cm; e) 3 dm.

Please I really need help

Answer 1

Answer:

1)P = 2 x(L+l) = 2 x (25+L)

2) Maintaing L= 25 cm

P= 2x (25+45) = 140 cm²

P= 2x (25+0,25m) =2x(25+25)= 100 cm²

P= 2x (25+650 mm) =2x(25+65)= 180 cm²

d) ambigous

P= 2x (25+3dm) = 2x (25+30)=110 cm²
