Answer 2

Correct Question :-

Find the perimeter and area of a rectangle whose length and breadth are 20 cm and 15 cm respectively.

Answer :-

• Perimeter of Rectangle = 70 cm.
• Area of Rectangle = 300 sq.cm.

Explanation :-

We know that,

Perimeter of Rectangle = 2(l + b).

Substitute the Values.

➠ Perimeter = 2(20 + 15).

➠ Perimeter = 2(35).

➠ Perimeter = 70 cm.

And,

Area of Rectangle = l × b.

➠ Area = 20 × 15.

➠ Area = 300 sq.cm.

Therefore,

• Perimeter of Rectangle = 70 cm.

• Area of Rectangle = 300 sq.cm.
