Answer:
10 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )
d = = 10 cm
<u><em>Using Pythagorean Theorem</em></u>
Where c is the length of diagonal, a and b are the length of the rest 2 sides
=>
Taking sqrt on both sides
=> c = 10 cm
