If a shape has a greater depth or an irregular perimeter, calculating its area and perimeter can be more challenging but also more interesting! Let's practice solving some problems involving perimeter and area. Write your answers in the spaces provided.Short Problems 1. A rectangular garden has a length of 15 meters and a width of 8 meters. - What is the perimeter of the garden? - What is the area of the garden? 2. A square has a side length of 7.5 cm. - What is the perimeter of the square? - What is the area of the square?
Word Problems 3. A farmer wants to fence a rectangular field. The field has a length of 20 meters and a width of 10 meters. - How much fencing will the farmer need to go around the field? - If the farmer decides to divide the field into two equal parts, what will be the perimeter of each smaller section? 4. Imagine you have a circular rug with a diameter of 4 meters. - What is the circumference (perimeter) of the rug? Use π = 3.14 for your calculation. - What is the area of the rug? 5. A triangle has sides of 9 cm, 12 cm, and 15 cm. - What is the perimeter of the triangle? - If the triangle is equilateral and each side is 10 cm, what would be its perimeter?
Challenge Problem 6. Design your own shape with a perimeter of 30 cm. - Draw the shape and label its sides: - What is the area of your shape? (Use any additional information you need to calculate it.) Great job solving these problems! You're getting better at understanding shapes and their measurements. Keep practicing and soon you'll be a math whiz! 😊
