Im pretty sure that it is 50
Answer:
69
Step-by-step explanation:
For a square and rectangle it is Area=length*width

to solve for j first you need to cross multiply;
j × 35 = 42 × 55
35j = 2,310
j = 2,310 ÷ 35 (did the inverse operation)
j = 66
Hope that helps :D
First you have to multiply 2x33 which is 66 then you have to add 1 which is 67 so the answer would be 67/2 I don’t know about the percent sign though
