Step-by-step explanation:Because even without knowing the lengths, you can tell that b+c is definitely bigger than a, and a+b is definitely bigger than c. So I guess you will just have to take your chances and guess.
It is a. A right triangle is proven to be a right triangle with its right angle. Line a and c forms the right angle. C and b are much longer than a, so it is fair to assume that their measurements are a bigger number. It can’t be b, because b + c < a doesn’t make sense as a is the smallest side and b and c are longer. C doesn’t make sense, as side b is longer than c. D doesn’t make sense as the triangle theorem states that the sum of two sides has to be greater than the longest side for it to be a triangle. This is obviously a triangle. So your final answer is a.
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
