Free Grade 7 Two-Dimensional Figures in a Plane Practice

Solve real-world and mathematical problems involving area, volume, and surface area of two-dimensional and three-dimensional objects. This includes calculating these measures for composite shapes.

Topic Overview

Definitive Answer: Solve real-world and mathematical problems involving area, volume, and surface area of two-dimensional and three-dimensional objects. This includes calculating these measures for composite shapes.

Hey there! Imagine you're painting a wall or laying new carpet. How much paint or carpet do you need? That's where **area** comes in! Area is the amount of flat space a two-dimensional shape covers. We measure it in square units. For a **rectangle**, like a basketball court, you multiply its length by its width (Area = length × width). A **square** is a special rectangle where all sides are equal, so you multiply side by side (Area = side × side). For a **triangle**, like a slice of pizza cut in half, you multiply its base by its height and then divide by two (Area = (base × height) / 2). Understanding area helps us solve many real-world problems, from home projects to sports fields!

Step-by-Step Examples

Example 1: A square patio has a side length of 9 yards. What is the area of the patio?
  1. **Step 1: Identify the shape and formula.** The patio is a square. The formula for the area of a square is: Area = side × side.
  2. **Step 2: Substitute the given value.** The side length is 9 yards. So, Area = 9 yards × 9 yards.
  3. **Step 3: Calculate the area.** Multiply the values: 9 × 9 = 81. Remember to include the units: square yards.
✓ Answer: 81 square yards
Example 2: A rectangular garden plot measures 12 meters long and 7 meters wide. What is the area of the garden plot?
  1. **Step 1: Identify the shape and formula.** The garden plot is a rectangle. The formula for the area of a rectangle is: Area = length × width.
  2. **Step 2: Substitute the given values.** The length is 12 meters and the width is 7 meters. So, Area = 12 meters × 7 meters.
  3. **Step 3: Calculate the area.** Multiply the values: 12 × 7 = 84. Remember to include the units: square meters.
✓ Answer: 84 square meters

Tips & Tricks

  • Remember, 'Area is Always R-U-L-E-D by Squares!' Think of covering a surface with square tiles.
