QUESTION:-

The side of rectangle are in the ratio 7:

5 and its perimeter is 120 cm. the length

of rectangle is -

ANSWER:-

RATIO= 7:5

RATIO= 7:5 PERI = 120 cm

RATIO= 7:5 PERI = 120 cm Length = ?

RATIO= 7:5 PERI = 120 cm Length = ? So ,

7x + 5x = 120 \\  \\ 12x = 120 \\  \\ x =  \frac{120}{12 }  \\  \\ x = 10 \\  \\ 7x = 7 \times 10 = 70 \\  \\ 5x = 5 \times 10 = 50 \\  \\

70cm = Length

70cm = Length 50 = Breadth

Step-by-step explanation:

Given:

Ratio between length and breadth which is:

7:5

Let the length and breadth be 7x and 5x.

Formula of perimeter of rectangle:

2(l + b) = perimeter

Perimeter given is 120 cm.

 =  > 2(7x + 5x) = 120

 =  > 2 \times 12x = 120

 =  > 24x = 120

 =  > x =  \frac{120}{24}

 =  > x = 5

Length = 7x

= 7 X 5 = 35 cm.

Breadth = 5x

= 5 X 5 = 25 cm.

Hence, length of the rectangle is 35 cm and breadth is 25 cm.
