Plz do not delete my questions. I will give you 30 points for these three questions. A thanks. And a 5 star rate. But in order for this to happen you have to make sure to SHOW YOUR WORK and MAKE SURE IT IS RIGHT. Then I will give you all of that. 1. Vikram is studying the square pyramid below. The first and second pictures are for this question.To find the surface area of the pyramid, in square inches, Vikram wrote SECOND PICTURE HERE. What error did Vikram make?He used the same expression for the area of all four lateral faces.He used the wrong expression to represent the area of the base of the pyramid.He used the wrong value as the height when he found the area of the lateral faces.He used an expression for surface area that only finds the total area of three faces.2. Tracy used the expression THIRD PICTURE GOES HERE to find the surface area, in square centimeters, of the rectangular pyramid below.This is for the fourth picture.Which statement best describes her work?Tracy’s answer will be incorrect because she forgot the factor 1/2 in the expression representing the area of the triangular faces.Tracy’s answer will be incorrect because the pyramid has five faces and her expression finds the sum of only three products.Tracy’s answer will be correct because she made use of the fact that 2 (1/2) = 1 in her expression.Tracy’s answer will be correct because a rectangular pyramid has only three faces and the expression finds the sum of three products.3. What is the total surface area of this rectangular pyramid?This is for the last picture______ square meters
