Perimeter=120
ED=x (length)
FE=4x (breadth)
Perimeter of rectangle= 2(l+b)
Given,
2(x+4x)=120
2x+8x=120
10x=120
x=120÷10
x=12
Therefore, value of x is 12
Answer: 12
<u>Step-by-step explanation:</u>
You are given that perimeter = 120, length (FE) = 4x, and width (ED) = x
P = 2L + 2w (P = perimeter, L = length, w = width)
120 = 2(4x) + 2(x)
120 = 8x + 2x
120 = 10x
<u>÷10 </u> <u> ÷10 </u>
12 = x
Answer:
21
Step-by-step explanation:
because you divide 9 byy 3 and you get 3 so then you do 7 x 3 7x3 is 21
20
i think, dont trust me tho
positive 29
