corresponding angles a) the constant by which a figure (or the dimensions of a figure) increases or decreases
scale factor b) corresponding sides of two similar triangles
proportional c) figures that have congruent angles and corresponding sides that are proportional to one another
similar polygons d) these corresponding parts are congruent, given two similar triangles
scale drawing e) a depiction of a real object with accurate sizes except they have all been reduced or enlarged

Part 1.Corresponding angles

 = (e) .Corresponding sides of two similar triangles.

Remember - The angles in matching corners are called Corresponding Angles.

Part 2.Scale factor

= (d).the constant by which a figure (or the dimensions of a figure) increases or decreases.

Part 3.Proportional

= (c).these corresponding parts are congruent, given two similar triangles.

Part 4.Similar polygons

= (a).figures that have congruent angles and corresponding sides that are proportional to one another.

Part 5.Scale drawing.

= (b).a depiction of a real object with accurate sizes except they have all been reduced or enlarged. 

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
