First, let’s calculate the length of the second leg. Multiply the length of the first one by 2.
a = 25 mm * 2 = 50 mm.
In order to calculate the area of a right-angled triangle, divide the product of two legs by 2.
S = (25 mm * 50 mm) ÷ 2 = 625 mm².
Answer: the area of a right-angled triangle is 625 mm².
