Answer:

41 units

Step-by-step explanation:

Pythagorean's  theorem,

Hypotenuse² = base² + adjacent²

Diagonal² = length² + width²

                 = 40² + 9²

                 = 1600 + 81 = 1681

Diagonal = √1681 = 41 units

➷ Work out the cost per gram

60/125 = 0.48

It costs 0.48 cents per gram

Multiply this by 100 to get the answer:

0.48 x 100 = 48

It would cost 48 cents
