0-8: Area

0-8: Area Example 1: Find the area of each figure A) A rectangle with a length of 7 yards and a width of 1 yard A = lw = (7)(1) = 7 The area is 7 square yards

0-8: Area Example 1: Find the area of each figure B) A square with a side length of 2 meters A = s2 = (2)2 = 4 The area is 4 square meters

0-8: Area Example 1: Find the area of each figure C) A parallelogram with a base of 11 feet and a height of 9 feet A = bh = (11)(9) = 99 The area is 99 square feet

0-8: Area Example 1: Find the area of each figure D) A triangle with a base of 12 millimeters and a height of 5 millimeters A = ½bh = ½(12)(5) = 30 The area is 30 square millimeters

0-8: Area The formula for the area of a circle is A = πr2 Example 2: Find each area to the nearest tenth A) The radius is 3 cm A = πr2 = π(3)2 ≈ 28.3 The area is about 28.3 square centimeters

0-8: Area The formula for the area of a circle is A = πr2 Example 2: Find each area to the nearest tenth A) The diameter is 21 m A = πr2 = π(10.5)2 ≈ 346.4 The area is about 346.4 square meters
