The ratio of the length and breadth of a rectangle is 5 is to 4and it's area is 180cm square find its length and breadth

15cm and 12cm

Step-by-step explanation:

From the question,The ratio of the length and breadth of a rectangle is 5 to 4

We assume The Lenght of the field= 5x

The breadth = 4x

Area= (5x × 4x)= 180

20x^2= 180

X^2=

X= √9

X=3cm

The Lenght of the field= 5×3= 15cm

The breadth = 4×3=12cm

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
