Question

Bazele unui trapez au lungimile de 35cm si 29cm, iar aria lui este de 256cm^2. Aflati inaltimea trapezului.

Answer 1

(B+b)*h/2=256cm²
(35cm+29cm)*h=2*256cm²
64cm*h=512cm²
h=512cm²:64cm
h=8cm

Answer 2

$A= \frac{(B+b)*h}{2} \\ 256= \frac{( 35+29)*h}{2} \\ 512=64h \\ h=512:64 \\ h=8 (cm)$
