Question

length of a rectangle is 8 meter less then twice its breath if the perimeter of the rectangle is 56cm find the lenght and breath​

Answer 1

Answer:

convert 8m into cm

8×100 = 800cm

Let's consider

Breadth of rectangle = x

length of rectangle = 2x-800

Perimeter of rectangle = 56

To find : length and breadth

so...

Let's solve.

Perimeter ofrectangle = 2(length + breadth )

56 = 2 ( 2x-800. + x )

56 /2 = 2x -800+ x

28 = 2x+x - 800

28 = 3x - 800

28 + 800 = 3x

828 = 3x

therefore ,

x = 828 /3

= 276

so. Breadth is 276 cm

Lenght = 2x - 800

2(276)-800

552 -800

-248 cm

so, Length is -248 cm

Breadth is 276 cm
