  A = (20 cm)(18 cm) +2(8 cm)(20 cm +18 cm)

Elina [12.6K]

Answer:

58.8

Step-by-step explanation:

- the word 'of' in maths means times

so 15.4% of the 382ml is the same as

382*15.4/100

to do that, you multiply 382 by 15.4 = 5882.8

then you divide that by 100= 58.828

and then you just round that of to 58.8
