Question

write the formulas of area and perimeter of rectangle, square also find length and breadth of rectangle when area and perimeter are given​

Answer 1

Here are the formulas for area and perimeter of a rectangle and square:

Rectangle:

Area = Length * Breadth

Perimeter = 2(Length + Breadth)

Square:

Area = Side * Side

Perimeter = 4 * Side

To find the length and breadth of a rectangle when the area (A) and perimeter (P) are given:

First, we can write two equations:

Area = Length * Breadth

Perimeter = 2(Length + Breadth)

Since we know A and P, we can substitute them in the equations and solve for Length and Breadth.

So, the steps are:

1) A = Length * Breadth (Given the area A)

2) P = 2(Length + Breadth) (Given the perimeter P)

3) Solve the two equations simultaneously to find Length and Breadth

Hope this explanation helps! Let me know if you have any other questions.

Answer 2

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
