Question

Find the length of diagonal of the rectangle whose sides are 16 cm and 12 cm​

Answer 1

Answer:

let its diagonal would be d

Pythagoras formula :

d^2 = 16^2 + 12^2

d^2 = 256 + 144

d^2 = 400

d= √400 = 20cm

so the length of diagonal is 20cm.

Answer 2

Answer: Length of of diagonal = 20 cm

Step-by-step explanation:As all the angles of the rectangle are 90°. And we given with the length and the breadth .

So we can use Pythagoras theorem

(Diagonal)^2= (length)^2 + (breadth)^2

(Diagonal)^2= (16)^2+(12)^2

Therefore diagonal = 20 cm
