Question

Q. Find the area of a book whose length is 108cm and breadth is 102cm​

Answer 1

Given:-

• Length of a book is 108 cm.
• Breadth of a book is 102 cm.

To find:-

• Area of a book.

Solution:-

Here,

• Length (l) = 108 cm
• Breadth (b) = 102 cm.

According to the question,

→ Area = length × breadth

→ A = l × b

→ A = 108 × 102

→ A = 11016 cm²

Hence,

• the area of a book is 11016 cm².

More Formulas:-

→ Perimeter of rectangle = 2(l + b)

→ Perimeter of square = 4 × side

→ Area of square = a²

→ Area of triangle = ½ × b × h

→ Area of parallelogram = b × h

Answer 2

● L-108cm

● B-102cm

area of recangle =l×b

=108×102

= 11016

area of book is = 11016
