7cm​

Answer 1

Correct Question :

›»› Find the diagonal of rectangle with length 15cm and breadth 8cm.

Answer :

›»› The diagonal of rectangle is 17 cm.

Given :

• Length of rectangle = 15 cm.
• Breadth of rectangle = 8 cm.

To Find :

• The diagonal of rectangle = ?

Solution :

To find the diagonal of rectangle, we use the formula:-

❰ Diagonal = √(l)² + (b)²❱

• Length = 15 cm.
• Breadth = 8 cm.

According to the given question,

On putting the given values in the formula, we get

→ Diagonal = √(15)² + (8)²

→ Diagonal = √225 + 64

→ Diagonal = √289

→ Diagonal = 17

Hence, the diagonal of rectangle is 17 cm.

Correct option is (A) 17 cm ✔

Extra Brainly Knowledge :

• Area of Rectangle = l * b.
• Perimeter of Rectangle = 2(l + b).
• Diagonal of Rectangle = √(l)² + (b)².
• Area of Square = a × a
• Perimeter of Square = 4 × a.
• Diagonal of Square = √2a.

Where,

• l is the Length in cm or m.
• b is the Breadth in cm or m.
• a is the Side in cm or m.
