Question

exercitiul 10 punctul c va rogg

Answer 1

MNPQ Dreptunghi => MN = QP = b si MQ = NP = B

2b + 2B = 80

MQ = 3QP - 2 => B = 3b - 2

Acum inlocuim

2b + 2(3b-2) = 80

2b + 6b - 4 = 80

8b = 8+4

8b = 84

b = $\frac{21}{4}$ => B = $\frac{63}{4}$ - 2 => B = $\frac{55}{4}$ => MQ = $\frac{55}{4}$
