Question

find the lenght of a diagonal of rectangule whose length is 8 cm and width is 6 cm​

Answer 1

Step-by-step explanation:

In rectangle ABCD,

If we construct a diagonal it will create a right - angled triangle

By the given condition,

In∆ADC

By Pythagoras theorem,

AD^2+DC^2= AC^2

6^2+8^2=AC^2

36+64=AC^2

100= AC^2

√100=AC .... ( taking sq.roots)

10=AC

therefore,

AC= 10cm
