I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
We need to find the area of the shape by breaking down it into 2 triangles and 1 rectangle.
=> the area of the rectangle : length*width = 7*4 =28 square units
=> the area of the triangles using : 1/2*length *width = 1/2*4*3 = 6 square units
Hence, the total area is: 28 + 6 + 6 = 40 square units
=> the number of quarts need purchased to stain the deck once:
= 40/8 = 5 quarts
Hope it will find you well.
