What’s one less than the quotient of a number and -5

Based on the merits of your question, this cannot be sloved and unless you know what the statement equals because we can't slove for two variables based on these merits. But here it is based on the merits:

THIS ONE ASSUMES THE NUMBER OF THE QUOTIENT AND WHAT IT EQUALS IS EQUAL

THIS ONE ASSUME THAT THEY ARE TWO DIFFERENT VALUES

You are told the middle part is a square, so all 4 sides are equal.

The height is shown as 4 feet, so the width of the square is also 4 feet.

This means the height of the 2 triangles is 7 - 4 = 3 feet, so each triangle is 1.5 feet high ( 3 feet / 2 = 1.5).

The area of the square is 4 x 4 = 16 square feet.

The area of 1 triangle is 1/2 x base x height = 1/2 x 4 x 1.5 = 3 square feet.

The total area = 16 + 3 + 3 = 22 square feet.
