### Activity Description

The worksheet shows the usage of area calculation and mathematical operations in real-life situations.

Storyline :

The student applied for a job "Precision Painting Estimator" job, they are given a new task as part of the application. The task is to find the total paint needed to paint all the walls of a given floor plan. The dimensions such as width, length, and height of the walls are given, what they need to find is the paintable wall area of each room separately. The trick is that the doors and windows are to be excluded from this calculation.

They will have to analyze the floor plan given, understand the number of doors and windows in every room, and then exclude this from the room's total wall area.

You can assign this worksheet to the classroom to reinforce the learning on area calculation, measurement, and mathematical operations. The activity is auto scored.

### Learning Objective

Students will use the area calculation they learned to solve a real world problem. They will also derive the relationship between perimeter and area.

### Teacher Tips

### Common Core: MATH

Geometry

Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

Geometry

Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

Geometry

Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
