Question

*What is the length of a rectangle with an area of ​​108 sq.cm. and the sides are in the ration 4:3?*​

Answer 1

Answer:

l=12

Step-by-step explanation:

l:b=4:3

l=4x

b=3x

area =108

l×b=108

4x×3x=108

12x^2=108

x^2=108/12

x^2=9

x=3

l=4x

l=4×3

l=12

Answer 2

Answer:

the answer is 12cm

Step-by-step explanation:

let we make sure that the length and breadth is 4x and 3x

area=l×b

108=4x×3x

108=12x×x

108/12=x×x

9=x×x

3=x

now we find length and breadth

4x=4×3

4x=12cm

3x=3×3

3x=9

so,the length is 12cm and the breadth is 9cm
