The length of the room is 2½ times the breadth. The perimeter of the room is 70 m. What are the length and breadth of the room.

Step-by-step explanation:

Let breadth of the room be 'x'

Let length of the room be ''

Perimeter ( P ) = 70 cm

Now, let's find the breadth of the room 'x '

Perimeter of rectangle =

plug the values

Collect the like terms

Calculate the product

Swap the sides of the equation

Divide both sides of the equation by 7

Calculate

Breadth = 10 cm

Now, Let's find the length of the room ' 2.5x '

Length of the room =

Plug the value of X

Calculate the product

Thus , The length and breadth of the room is 25 cm and 10 cm respectively.

Hope this helps..

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
