Question

I think its b

Answer 1

Assuming that the rug is rectangular in shape, therefore the formula of area is:

A = l w                                   ---> 1

where l is the length of the rug and w is the width of the rug

 

We are given that the width of the rug is 5 feet less than the length, therefore:

w = l – 5                                ---> 2

 

Combining equations 1 and 2 and knowing that A = 150 will give us:

l (l – 5) = 150

 

In the given choices, l = x, therefore:

x (x – 5) = 150

 

Hence the correct answer is the 1st one (A)
