Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y
4407 × 100/39=y
11300=y

Answer:
580 cm^2
Step-by-step explanation:
First, find the area of the front and back. 20*10=200
There are 2 sides with 20*10 ( front and back) so we can multiply by 2. 200*2=400
Then, the sides. 3*20=60*2=120
Then, the top and bottom 10*3=30*2=60
400+120+60=580
