You are not allowed to use a calculator in this question. В A (4V3+1) cm - diagram shows triangle ABC with side 4B = (4V3 + 1) cm. Angle B is a right angle. It the area of this triangle is cm2. 47 2 Find the length of the side BC in the form (aV3 + b) cm, where a and b are integers. Hence find the length of the side AC in the form p V2 cm, where p is an integer.

Determine the area of the triangle with vertices (−2, −2, 4), (3, −4, 2), and (-7, 1, 3). Use the square root symbol '√' where needed to give an exact value for your answer. Area - 0
