Question

lenghth of rectangular field is 6 times its breath...if the lenghth of the field is 120 cm,find the breath and perameter of field...​

Answer 1

Answer:

Let length of the rectangle be L

Breadth = B

It is given that L = 6 × B

Also the length is 120 cm

∴ The breadth of the rectangle is:

L = 6 × B

B = L/6

B = 120/6

B = 20 cm

∴ The perimeter of the rectangular field is = 2 × (L + B)

                                                                      = 2 × (120 + 20)

                                                                      = 2 × 140

                                                                      =  280 cm

Answer 2

☞Correct Question:

Length of rectangular field is 6 times its breadth. If the length of the field is 120 cm,find the breadth and perimeter of field.

☞Required Answer:

=> Breadth of rectangular field = 20cm

=> Perimeter of rectangular field = 280cm².

☞Solution:

Given

•Length of rectangular field is 6 times its breadth.

•Length = 120cm

To find:

•Breadth of rectangular field

•Perimeter of rectangular field

─────────────

☞How to solve :

✒It is given that length of field is 6 times its breadth.

Length = 120cm.

=>Let breadth be 'x'

✒According to ques:

6 × x = 120

x = $\sf\dfrac{120}{6}$

x = 20

Therefore, Breadth of rectangular field = 20cm

─────────────

☞Formula used :

Perimeter of rectangle = 2(l + b)

Length = 120cm

Breadth = 20cm

Perimeter of rectangular field = 2(l + b)

= 2 × (120 + 20)cm

= 2 × (140)cm

= 280cm².

Therefore, Perimeter of rectangular field = 280cm².
