Question

Find the diagonal of a rectangle whose length and breadth are 16 cm and 12 cm respectively

Answer 1

Step-by-step explanation:

the size of diagonal is 20cm

Answer 2

Answer:

37

Step-by-step explanation:

Let □ ◻ABCD be the given rectangle.

AB = 12 cm, BC 35 cm

In ∆ABC, ∠B = 90° [Angle of a rectangle]

∴ AC = AB + BC [Pythagoras theorem]

= 122 + 352 = 144 + 1225 = 1369

∴ AC = √ 1369 1369 [Taking square root of both sides]

= 37 cm ∴ The diagonal of the rectangle is 37 cm
