Question

The length & the breadth of a rectangleare in the ratio 4:3 & it's perimeter is 84cm.
Find the length & the breadth. ​

Answer 1

Answer:

Length = 24cm, Breadth = 18cm

Step-by-step explanation:

As the ratios is 4:3 so , let the ratios be 4x and 3x

perimeter = 84cm

perimeter = 2(l+b)

= 2(4x+3x)

14x = 84

x = 6

therefore, 4x = 24 cm and 3x = 18cm

Answer 2

Answer:

Let,length and breadth be x

4:3x=84

4\3=84x

x/3=84×4

x=84×4/3

x=112

length=112×4=448

breadth=112×3=336

therefore,length and breadth is 448 and 336
