Area of Polygons

Front

What is the formula to calculate the area of a rectangle?

Back

Area = Length × Width

Front

What is the area of a triangle with a base of 10 feet and a height of 5 feet?

Back

Area = 0.5 × Base × Height = 0.5 × 10 × 5 = 25 square feet

Front

If a square has a side length of 4 feet, what is its area?

Back

Area = Side × Side = 4 × 4 = 16 square feet

Front

What is the area of a rectangle that is 7 feet long and 4 feet wide?

Back

Area = 7 × 4 = 28 square feet

Front

How do you find the area of a polygon?

Back

Divide the polygon into simpler shapes (like triangles and rectangles), calculate their areas, and sum them up.

Front

What is the area of a circle with a radius of 3 feet?

Back

Area = π × Radius² ≈ 3.14 × 3² ≈ 28.26 square feet

Front

What is the area of a parallelogram with a base of 6 feet and a height of 4 feet?

Back

Area = Base × Height = 6 × 4 = 24 square feet

Front

If the area of a rectangle is 40 square feet and the width is 5 feet, what is the length?

Back

Length = Area ÷ Width = 40 ÷ 5 = 8 feet

Front

What is the area of a trapezoid with bases of 5 feet and 7 feet, and a height of 4 feet?

Back

Area = 0.5 × (Base1 + Base2) × Height = 0.5 × (5 + 7) × 4 = 24 square feet

Front

What is the area of a rectangle with a length of 12 feet and a width of 8 feet?

Back

Area = 12 × 8 = 96 square feet
