A survey of a plot of land is shown. The plot is to have a hedge along its border. Calculate how many metres of hedge are needed, to the nearest tenth of a metre?

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

question: the type of image formed by a convex lens is determined by the objects?

answer: it depends on the shape of the lens and the position of the object.

explanation: because if it was not positioned correctly it would have a diffrent image of what you were expecting to see
