Question

1. the total area of this shape is 44 square inches. the area of the triangle is 20 square inches. write and solve an equation to find the area of the rectangle.

Explanation:

Step1: Set up the equation

Let the area of the rectangle be $x$. The total area is the sum of the area of the triangle and the area of the rectangle. So the equation is $x + 20=44$.

Step2: Solve the equation

Subtract 20 from both sides of the equation: $x+20 - 20=44 - 20$.

Answer:

$x = 24$ square inches
