Answer:
The second one
Step-by-step explanation:
1/4 goes into 2 2 /4
Means 2 2/4 divided by 1/4
Change 2 2 /4 to improper fraction. = (2*2 + 4)/4 = 10/4
10/4 ÷ 1/4
10/4 × 4/1
= 10
So it is 10.
We have to factor becasue
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width
we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width
