Question

The sum of the length and width of a rectangular table is 35 m. Find the perimeter of the table
and the dimension of the table if the difference between the length and the width is 5 m.​

Answer 1

Answer:

50m is the perimeter. Hope it will help you...

Answer 2

Answer:

Perimeter of a rectangular table = 70 m

Length of a rectangular table = 20 m

Width of a rectangular table = 15 m

Step-by-step explanation:

Given that-

The sum of length and width of a rectangular table = 35 m

Difference between length and width = 5 m

Let x and y be the length and width of a rectangular table.

Then according to question-

x + y = 35             --------------------- 1

x - y = 5                --------------------- 2

Perimeter =?

We know that-

Perimeter of a rectangle = 2(length + width)

                                      = 2(x + y)

                                      = 2×35

Perimeter of a rectangular table = 70 m

Adding equation 1 and 2

We have-

x + y + x - y = 35 + 5

2x = 40

x = 20

So, length of a rectangular table = 20 m

Put x = 20 in equation 2

x - y = 5

20 - y = 5

20 - 5 = y

y = 15

So, width of a rectangular table = 15 m
