Step-by-step explanation:
5 1/2×2 1/3
5 1/2=11/2
2 1/3=7/3
11/2×7/3=77/6
77/6= 12 5/6
The answer is D.
In the given question it is given that the length of the rectangle is 5.5 cm and the area of the rectangle is 220 cm^2.
Length of the rectangle = 5.5 cm
Area of the rectangle = 220 cm^2
Then we already know that
Area of a rectangle = Length * width
So Width of the rectangle = Area of the rectangle/ Length
= 220/5.5
= 2200/55
= 40
So the width of the rectangle is 40 cm.<span>Hope
