D+b(3) just put them all together
Answer:
Sample Response: 13
Step-by-step explanation:
4 is equal to 1.75. I would plot 1.5 and 1.75 between 1 and 2, but 1.75 would be closer to 2. Since 1.75 is further to the right, it is greater than 1.5.
Let us assume the width of the rectangle = x
Then Length of the rectangle = 4x + 9.7
Perimeter of the rectangle = 91.4 cm
Then
91.4 = 2[x + 4x + 9.7]
91.4 = 2[5x + 9.7]
91.4 = 10x + 19.4
91.4 - 19.4 = 10x
10x = 72
x = 7.2
So
Width of the rectangle = 7.2 cm
Length of the rectangle = 4x + 9.7
= 28.8 + 9.7
= 38.5 cm
