This video explains how areas are connected for similar shapes. It also covers surface areas.
Similar Shapes GCSE Maths Steps, Examples & Worksheet
Two solids are similar if they are the same type of solid and their corresponding radii, heights, base lengths, widths, etc. are proportional. Surface Areas of Similar Solids. In two dimensions, when two shapes are similar, the ratio of their areas is the square of the scale factor. A comparable relationship holds in three dimensions as well.

Edexcel Transformations - Edexcel Scale factors of similar shapes - Higher Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected,.
G19a Lengths, areas and volumes in similar shapes
What are similar shapes? Similar shapes are enlargements of each other using a scale factor. All the corresponding angles in the similar shapes are equal and the corresponding lengths are in the same ratio. E.g. These two rectangles are similar shapes. The scale factor of enlargement from shape A to shape B is 2 2. The angles are all 90^o 90o

Area of Similar Figures IGCSE at Mathematics Realm
To find the area of two similar shapes we can use the knowledge that the ratio of their areas is equal to the ratio of the square of their respective sides. Let us take an example; ABC \ (\sim\) DEF So their corresponding parts must be proportional \ (\frac {AB} {DE}=\frac {AC} {DF}=\frac {BC} {EF}\)
