Question

the length of the rectangular field is 3 times its breadth if the area of the field is 147sqm find its length and breadth​

Answer 1

Step-by-step explanation:

LET LENGTH BE L AND BREATH BE B

ACC. TO QUESTION,

L=3B -----------(1)

ALSO,

L*B = 147 ----------( 2)

FROM (1),

3B*B = 147

3B² = 147

B² = 147/3

B²= 49

B =√49

B= 7

ALSO L = 3B = 3*7 = 21

Answer 2

Question:-

• The length of the rectangular field is 3 times its breadth if the area of the field is 147sqm find its length and breadth.

Given that:-

• The length is three times it's breadth.
• Area is rectangle is 147sqm.

To Find:-

• Find the length and breadth.

Let us assume:-

• Breadth be ‘ x ’
• Length be ‘ 3x ’

Solution:-

➝ Area = length × breadth

➝ 147 = 3x × x

➝ 147 = 3x²

➝ x² = 147/3

➝ x² = 49

➝ x = √49

➝ x = 7

Hence ,

• Breadth is x = 7 cm
• Length is 3x = 21 cm
