Question

Calculate the length of a diagonal of a rectangle whose side are 8cm and 6cm

Answer 1

Answer:

10cm.

Step-by-step explanation:

Step 1. We have to consider a pair of adjacent sides as height and base

2. Use pythagoras theorm that is (hypotenuse)²=(base)²+(height)². It can be done by considering a rectangle as two connected triangles.

3. From the step above, we observe that (diagonal)²=(8)²+(6)². therefore, (diagonal)²=64+36. therefore, diagonal²=100.

3.As we know that 100 is the square of 10, 10cm is the ans.
