Question

In paralelogramul ABCD construim inaltimile AE, E apartine BC , si AF, F apartine CD .

Aflati aria paralelogramului daca:

a)BC=8 cmsi AE =11 cm

b) AB=12cm si AF= 7 cm

Answer 1

Răspuns:

Aria unui paralelogtam=baza×inaltime=>

a) aria=8×11=88cm

b) aria=12×7=84cm

Answer 2

$\it a)\ \ \mathcal{A}=BC\cdot AE=8\cdot11=88\ cm^2\\ \\ b)\ \ \mathcal{A}=CD\cdot AF=AB\cdot AF = 12\cdot7=84\ cm^2$
