어 늘어나다

increased by that much

늘어나다 is a figure going up on its own, and all four lines here are the same news formula: a basis for comparison, a percentage, then 늘어난. 전년 동기 대비 62%가 늘어난 매출액입니다 is "revenue, up 62% on the same period last year"; 10년 전에 비해서 거의 50%가 늘어난 수치입니다 compares against a decade ago. Every line is formal reporting in the -습니다 style, with no casual use shown at all. 늘리다 is someone deliberately increasing something; 늘어나다 is the number rising.
