Question

the length and breadth of a 5cm rectangle in the ratio of 4:7 length is 15cm more than breadth. what are the length and breadth​

Answer 1

Step-by-step explanation:

Length = 35 Cm, Breadth = 20 cm.if x is length & y is breadth.

Then 4x=7y, x=y+15,

If we replace x in the equation we get

7y=4y+4*15

3y=60 cm

y= 20 cm

x= 35 cm

Answer 2

Length = 35 ¢m

Breadth = 20¢m

Then 4x = 7y, x = y + 15,

if we replace X in the eqn

7y = 4y + 4 * 15

3y = 60¢m

y= 60 / 3 ¢m

y = 20¢m

x= 35¢m
