Answer:
8/5 or 1 3/5 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
The area is 4/5 and the width is 1/2
4/5 = 1/2 *l
Multiply each side by 2
2*4/5 = 2*1/2 *l
8/5 = l
Changing to a mixed number
l = 1 3/5
Answer:
57.04
Step-by-step explanation:
2 x 1.2 = 2.4
2.4 x 2.4 = 5.76
5.76 + 9 = 14.76
14.76 x 2 = 29.52
5.76 + 8 = 13.76
13.76 x 2 = 27.52
29.52 + 27.52 = 57.04
