The length of a side and the corresponding height of a triangle is (x+3)cm and (2x-5)cmm respectively. Given that the area of the triangle is 20cm square find the value of X.

Answer:A= (a×h)/2

(x+3)(2x-5):2=20

(x+3)(2x-5)= 40

2x^2+x-55=0

∆=441

X1= -4 nu este soluție,

X2 = 13/2.

Rsp. X= 13/2
