By adding all the numbers and dividing by 7 ( the amount of numbers) you know that the answer will be about 166.3
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
It has to be 5 because 2.5 is half so the other half 2.5 .so 2.5 +2.5 =5
B. 12 assuming that it is a right triangle :)
