What is the perimeter of rectangle if it’s one side is 24 cm and length of diagonal is 25 cm?1. 60 cm2. 62 cm3. 70 cm4. 72 cm

Answer» Correct Answer - Option 2 : 62 cm

Given:

Length of diagonal of rectangle is 25 cm

And one of its sides is 24 cm

Formula used/Concept Used:

Length of diagonal of rectangle = √(length2 + Breadth2)

Perimeter of rectangle = 2 × (Length + Breadth)

Calculation:

Let the other side of rectangle is x

∴ 25 = √242 + x2

Squaring both sides

⇒ x2 = 49

⇒ x = 7 cm

Now, Perimeter of rectangle = 2 × (24 + 7) = 2 × 31 = 62 cm

∴ Perimeter of rectangle is 62 cm
