Answer: 21cm
Step-by-step explanation:
To find the area of a rectangle you just multiply the length by the width. In this case we have 12(width) x ?(length) = 252. To solve we would just divide the area by the known measurement to find the missing one, so 252/12 =21cm
1+3x /4= 5/2
1+3x = 5*4/2
1+3x =10
3x =9
x = 3
