Question

The breadth of a rectangle is 5cm and one of its diagonal measures 13cm. Find the perimeter of the rectangle.

Answer 1

Step-by-step explanation:

Solution: As we know that all angles of a rectangle are 90° that means it forms a right-angled triangle when divided by a diagonal. "Perimeter of the rectangle" = 34 cm.

Answer 2

Answer:

Step-by-step explanation:We can use pythagorous theorem

diagonal = 13 cm

breadth = 5cm

length= x

13

5$x^{2} =169\\x^{2} x^{2} =25\\169 -25 =144\\\sqrt{x} \\144\sqrt{x} =12$
