Question

the dimension of lawn are in the ratio 4:1 and its area is 2500m2.What is the length of the lawn?

Answer 1

4x*1x=2500m2
4x2=2500m2
2500m2/4m2
x2=625
x=√625
x=25
Therefore,breadth=x=25
And breadth=4x=4*25=100

Answer 2

Answer:

Length is 100m and Breadth is 25m

Step-by-step explanation:

The dimensions of lawn are in the ratio of 4:1

Let the number be x

So length=4x and breadth=x

Area of the lawn(rectangular)=2500m square

lb=2500m square

4x*x=2500

4x square=2500

x square=2500/4

x square =625

x=square root of 625

x=25m

So Length=4x=4(25)=100m and Breadth=x=25m
