What is the length of a rectangle its breadth is 10 cm and diagonal is 26 cm?
Use Pythagoras’ Theorem:
a^2 + b^2 = c^2 where a and b are two sides of a triangle at right angles to each other and c is the hypotenuse (longest side).
In this case we need to rearrange the formula for c^2 - b^2 = a^2
This becomes 26^2 - 10^2 = a^2
So: 676 - 100 = a^2 so 576 = a^2.
Therefore, the unknown length of the rectangle is sqrt(576). Very neatly, this happens to be 24.
24cm (better include the units now it’s the final answer).
