Answer:
yes 1+1=2
Step-by-step explanation:
L = 3 + 2w
Find the width
Area = 54
l × w = 54
(3 + 2w) × w = 54
3w + 2w^2 = 54
2w^2 + 3w - 54 = 0
(2w - 9)(w + 6) = 0
w = 9/2 or w = -6 (width shouldn't be negative)
w = 9/2
w = 4.5 m
Find the length
l = 3 + 2w
l = 3 + 2(4.5)
l = 3 + 9
l = 12 m
The width is 4.5 m, the length is 12 m
88957440/2=1/7 of the earths surface
44478720=1/7 of the earths surface
222393600km^2 is how much water covers the earth
92 = 2 x 2 x 23
hope this helps
