Given the rectangle ABCD and the triangle BEC. Find the value of x such that the ratio of the area of the rectangle to the area of the triangle BEC is 7:3.
Answer: x = ....... cm.
ta co ti so:
\(\frac{S_{abcd}}{S_{bec}}=\frac{7}{3}\Leftrightarrow\frac{ab.bc}{\frac{x.bc}{2}}=\frac{7}{3}\Leftrightarrow\frac{2ab}{x}=\frac{7}{3}\)
\(\Leftrightarrow\)\(\Leftrightarrow\frac{2.7}{x}=\frac{7}{3}\Leftrightarrow\frac{2}{x}=\frac{1}{3}\Leftrightarrow x=6\)
Giải hộ mình bai toán này nhé:
