Question

What is the length of the rectangle if it’s Bredth is 10 cm and diagonal is 26 cm

Answer 1

Answer:

24

Step-by-step explanation:

Use Pythagoras’ Theorem:

a² + b² = c² where a and b are two sides of a triangle at right angles to each other and c is the hypotenuse (longest side).( which is the diagonal in this question )

In this case we need to rearrange the formula for c² - b² = a²

This becomes 26² - 10²= a²

So: 676 - 100 = a² so 576 = a²

Therefore, the unknown length of the rectangle is √(576).  this happens to be 24.
