Solving Equations and Area Problems

The video tutorial explains how to solve a geometry problem involving an L-shaped figure with a given area of 12 cm². The problem is approached by dividing the L-shape into two rectangles, calculating their areas, and setting up an equation to solve for the unknown variable X. The solution involves basic algebraic manipulation to find that X equals 1.5 cm.

What is the given area of the L-shape in the problem?

• 20 cm²

• 15 cm²

• 12 cm²

• 10 cm²

What is the task in the problem regarding the L-shape?

• Find the perimeter

• Find the area

• Find the value of X

• Find the volume

How is the L-shape divided to simplify the problem?

• Into two triangles

• Into two squares

• Into two rectangles

What is the purpose of dividing the L-shape into two rectangles?

• To change the shape

• To find the perimeter

• To simplify the calculation

• To find the volume

What is the area of the top rectangle in terms of X?

• X

• 2X

• 3X

• 4X

What is the expression for the area of the lower rectangle?

• 5X + 10

• 3X + 6

• 2X + 4

• 4X + 8

What equation is formed by summing the areas of the two rectangles?

• X + 3X + 6 = 12

• 2X + 4X = 12

• 4X + 8 = 12

• 3X + 5 = 12

What is the simplified form of the equation X + 3X + 6 = 12?

• 7X + 6 = 12

• 6X + 6 = 12

• 5X + 6 = 12

• 4X + 6 = 12

What mathematical operation is used to combine the areas of the two rectangles?

• Division

• Subtraction

• Addition

• Multiplication

What is the first step in solving the equation 4X + 6 = 12?

• Subtract 6 from both sides

• Divide both sides by 4

• Add 6 to both sides

• Multiply both sides by 4
