Question

) A rectangular land is having its length 55 m and breadth 48 m. If the cost of 1 sq.m of the land is


Rs.2400, then what will be the cost of the land?​

Answer 1

Answer:

The formula of perimeter and area of rectangle are explained step-by-step with solved examples.

If l denotes the length and b denotes the breadth of the rectangle, then the

Perimeter and Area of Rectangle

4Save

● Perimeter of the rectangle = 2(l + b) units

● Length of the rectangle = P2 - b units

● Breadth of the rectangle = P2 - l units

● Area of the rectangle = l × b sq. units.

● Length of the rectangle = Ab units .

● Breadth of the rectangle = Al units

● Diagonal of the rectangle = l2+b2−−−−−√ units

Let us consider a rectangle of length 'a' units and breadth 'b' units.

Perimeter of Rectangle

Therefore, perimeter of the rectangle ABCD

= (AB + BC + CD + DA) units

= (a + b + a + b) units

= (2a + 2b) units

= 2 (a + b) units

Therefore, perimeter of the rectangle = 2 (length + breadth) units

We know that the area of the rectangle is given by

Area = length × breadth

A = a × b square units

⇒ a = Ab, i.e., length of the rectangle = Areabreadth

And b = Aa, i.e., breadth of the rectangle = Arealength
