The equation that can be used to find the value of x is (2.5x+1.5)4=36, and the value of x is 3.
What is the area of a rectangle?
The area of a rectangle is the product of its length and breadth. It is given by the formula,
Area of rectangle = Length × width
Given the length of the rectangle is 2.5x+1.5, while the width is 4. Also, it is mentioned in the question that the area of the rectangle is 36 square units. Therefore, we can write the area of the rectangle as,
[tex](2.5 x+1.5) \times 4 = 36\\\\(2.5 x \times 4) +(1.5\times 4) = 36\\\\10x + 6=36\\\\x = \dfrac{36-6}{10}\\\\x = 3[/tex]
Hence, the equation that can be used to find the value of x is (2.5x+1.5)4=36, and the value of x is 3.
