Question

The length of a rectangle is 4 cm and each of its diagonal measures 5 cm. find its breatdth.

Answer 1

We can find the length by using Pythagoras theorem.

Answer 2

The length of diagonal = 5cm

Length of rectangle = 4cm

Let the breadth be x.

To find the breadth , we will use Pythagorean theorem →

5² = 4²+x²

or, 25 = 16+x²

or, x² = 25-16

or, x²= 9

or, ✓x² = ✓9

or, x = 3cm

Answer→ The breadth of rectangle is 3cm
