Question

7. Find the perimeter of the rectangle whose length is 40 cm and a diagonal is 41 cm.​

Answer 1

Answer:

l =40

d =41

p=98 cm. .........

Answer 2

=> Given that length of the side of the rectangle is L = 40 cm and

=> The length of a diagonal is d = 41 cm

=> Let Breadth be bcm

=> Therefore, L² + b² = d²

=> 40² + b² = 41²

=> b² = 81

=> b = 9 cm

=> We know that the perimeter of the rectangle is 2 ( l + b ) = 2 ( 40 + 9 )

=> 98 cm
