Answer 1

Answer:

Perimeter of Sanya's card = Sum of all its sides = 10 + 8 + 10 + 8 = 36 cm

Length of Manav's card = 11 cm

Perimeter of his card = 44 cm

We have to find the width of Manav's card.

Perimeter of card = Sum of all its sides

= 11 + 11 + sum of 2 other sides

= 22 + sum of 2 other sides

Now, sum of two other sides = 44 − 22

= 22 cm

The two other sides of the greeting cards are width.

So, width of Manav's card = 22 ÷ 2

= 11 cm

Width of Aarushi's card = 8 cm

Area of the card = 80 square cm

Now, we have to find length of the card.

Area of card = Length of card × 8 cm = 80 square cm

So, on dividing the area of card by its width, we can get its length.

Therefore, length of Aarushi's card = 80 ÷ 8

= 10 cm

Whose card Length Width Perimeter Area

Sanya 10 cm 8 cm 36 cm 80 square cm

Manav 11 cm 11 cm 44 cm 121 square cm

Aarushi 10 cm 8 cm 36 cm 80 square cm

Kabir 10 cm
