I think the answer is 37.7
Answer:
D
Step-by-step explanation:
The pattern here is doubling each number.
Sequence to the seventh term:
Answer: c) 64
Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60
4x + 8y = 40
4x + 8(0.8) = 40
4x + 6.4 = 40
40 - 6.4 = 33.6
33.6 / 4 = x
33.6 / 4 = 8.4
The answer option 2, 8.4
