Answer 2

Answer:

• The area of the rectangle = 77 cm²

Given:

• The length of the rectangle is 4cm more than its breadth. the perimeter of the rectangle is 36cm.

Need to find:

• The area of the rectangle = ?

Solution:

Let,

• The breadth of the rectangle = y

Then,

• The length of the rectangle = (y + 4)

According to the question:

➜ 2 × [y + (y + 4)] = 36

➜ 2y + 4 = 18

➜ y = 7

Now,

• The breadth of rectangle = 7 cm
• Length of the rectangle = 7 + 4
• Length of the rectangle = 11 cm

Therefore:

• The area of the rectangle = 7 × 11
• The area of the rectangle = 77 cm²
