Question

Find the length of the diagonal of a rectangle whose sides are 6 cm and 12 cm.

Answer 1

Answer:

Step-by-step explanation:

Here, length = 12

Breadth= 6

Construction:- join the diagonal

Calculation:- let us consider []ABCD is the rectangle and AC is the diagonal.

In ∆ABC angle ABC = 90°

Therefore by Pythagoras theorem

AC²=AB²+BC²

=(12)²+(6)²

=144+36

=180

THEREFORE (AC) = √180

=6√5 units

Hence the length of the diagonal of the rectangle with sides 12& 6 is

=>[6√5]<=
