Answer:
Area of the rectangle = 1056 square units
Step-by-step explanation:
Rectangle published could be dissected into nine different squares with different sizes.
Area of the squares with different measure of sides will be,
For side length = 1 unit
Area of the square = (Side)²
= 1²
= 1 square units
For side length = 4 units
Area of the square = 4² = 16 units²
For side length = 7 units
Area of the square = 7² = 49 units²
For side length = 8 units
Area of the square = 8² = 64 units²
For side length = 9 units
Area of the square = 9² = 81 square units
For side length = 10 units
Area of the square = 10² = 100 square units
For side length = 14 units
Area of the square = 14² = 196 square units
For side length = 15 units
Area of the square = 15² = 225 square units
For side length = 18 units
Area of the square = 18² = 324 square units
Total area of the rectangle by adding these 9 squares
= 1 + 16 + 49 + 64 + 81 + 100 + 196 + 225 + 324
= 1056 square units
tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
