Width = 5x
length = 7x
Perimeter = 10x + 14x = 24x = 96cm
x = 96/24 = 4cm
width = 5x = 20cm
length = 7x = 28cm
Area = (20cm x 28cm) = 560 cm²
Answer:
2 3/6
Step-by-step explanation:
You must turn 1 2/3 and 1 1/2 into improper fractions. You then multiply them and get an answer of 15/6, but since 6 can go into 15 twice (6x2=12+3=15), you get a whole of 2 and 3/6.
The expression would be 19x-9. The reason is because if you think about it, it says that there is 9 less than 19x (x would be the unknown number) I hope this helps! ^-^
