Question

a rectangular sheet of paper is 15×3+1cm long and 12×2+1cm wide . Find its perimeter.​

Answer 1

Answer:

Rectangle

Step-by-step explanation:

In mathematics, the rectangle is a two-dimensional figure with four sides. It is considered as a quadrilateral. The opposite sides of the rectangle are of equal measures and each interior angle measures 90 degrees. The perimeter of the rectangle is equal to the sum of the four sides of the rectangle. Since the opposite side are equal measures, the perimeter of a rectangle formula is given by

The perimeter of a rectangle, P = 2 (Length + Width) units.

P=2(l+w)=2·(46+25)=142

Answer 2

Given :

• Length of Sheet = 15 × 3 + 1 cm
• Breadth of Sheet = 12 × 2 + 1 cm

To find :

• its perimeter.​

Solution :

⇒ Let's simplify the length and breadth.

→ Length of Sheet = 15 × 3 + 1 cm

→ 45 + 1 cm

→ 46 cm

→ Breadth of Sheet = 12 × 2 + 1 cm

→ 24 + 1 cm

→ 25 cm

⇒ Let's find the Perimeter of the sheet.

→ Perimeter of Rectangular sheet = (2 × length) + (2 × breadth)

→ (2 × 46) + (2 × 25)

→ 92 + 50

→ 142 cm

• Therefore, the Perimeter of the rectangular sheet is 142 cm.
