Answer (1)
Answer:The formula for the perimeter of a rectangle is P = 2l + 2w, where 'l' is the length and 'w' is the width. Let's calculate the perimeter for each case: l = 40 cm, w = 25 cmP = 2(40 cm) + 2(25 cm) = 80 cm + 50 cm = 130 cml = 6.5 m, w = 7.5 mP = 2(6.5 m) + 2(7.5 m) = 13 m + 15 m = 28 ml = 75 cm, w = 40 cmP = 2(75 cm) + 2(40 cm) = 150 cm + 80 cm = 230 cml = 125 cm, w = 50 cmP = 2(125 cm) + 2(50 cm) = 250 cm + 100 cm = 350 cml = 48 cm, w = 2 cmP = 2(48 cm) + 2(2 cm) = 96 cm + 4 cm = 100 cm
