Round the number 4.0875 two decimal places
so

A) 22.5 cm, 30 cm, and 37.5 cm
Divide 90 by 12 and multiply by three to check if any triplet has the answer in it. In this case only A
I think you would multiply 14m x 9m which is 126m and then you would multiply 2.4m and 3.8m which is 9.12m. Last you would subtract 9.12m from 126m which is 116.88m...I’m sry if this isn’t correct
Of course you already know everything parallel sides are equals
therefore the value of each variables will be as following :
left side = right side
3y-6=24
3y=24+6
3y=30
y=30/3
y=10

5x+2=12
5x=12-2
5x=10
x=10/5
x=2
