Question

the length and the breath of a rectangle are in the ratio of 5:7 if it's perimeter is 120 find it's area​

Answer 1

Answer:

Step-by-step explanation:

Let the length and breadth be 5x or 7x

Perimeter =2(l+b)

120=2(5x+7x)

120=10x+14x

120=24x

120/24=x

5=x

Length = 5*5=25

Breadth =7*5=35

Area=l*b

Area= 25*35

Area=875

Since you have not given the units in the question so I don't put them. If the answer is correct. So please mark the answer as Brainliest answer really needed for that.

Answer 2

Each side of the rectangle should be 5+7+5+7= 24 units.
24 units= 120
1 unit = 120/24 = 5
So the length = 5*5=25
Breadth= 5*7=35
So, the area= l*b = 25*35 = 875
There should be a unit like cm or m..but this will be the answer.
