Question

ABCD is a rectangle with AB =12cm BC=5cm Find the AC?​

Answer 1

Answer:

Since ABCD is a rectangle

So each angle of the rectangle is 90°

So ABC is a right angled triangle

Now AB =12cm, BC=5cm

We have by Pythagorean Theorem

AC² = AB² + BC²

➙ AC² = 12² + 5² = 144 + 25 = 169

➙ AC = 13

HENCE AC = 13 cm

Answer 2

Answer:

Step-by-step explanation:

Answer:

Since ABCD is a rectangle

So each angle of the rectangle is 90°

So ABC is a right angled triangle

Now AB =12cm, BC=5cm

We have by Pythagorean Theorem

AC² = AB² + BC²

➙ AC² = 12² + 5² = 144 + 25 = 169

➙ AC = 13

HENCE AC = 13 cm
