The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional like a carpet or an area rug. A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: where is the base, is the height, and · means multiply. The base and height of a parallelogram must be perpendicular. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height.Example 1: Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters. Solution: = (12 cm) · (5 cm) = 60 cm2 ---- Example 2: Find the area of a parallelogram with a base of 7 inches and a height of 10 inches. Solution: = (7 in) · (10 in) = 70 in2 ---- Example 3: The area of a parallelogram is 24 square centimeters and the base is 4 centimeters. Find the height. Solution: 24 cm2 = (4 cm) · 24 cm2 ÷ (4 cm) = = 6 cm ---- Summary: Given the base and height of a parallelogram, we can find the area. Given the area of a parallelogram and either the base or the height, we can find the missing dimension. The formula for area of a parallelogram is: where is the base, is the height, and · means multiply."1+1 =?""Have Fun"

The lengths of the sides of a shape with more than 3 sides does not provide enough information to determine its area.
Area of a parallelogram is base*height 15*7=105 105 square centimeters
If it's a rectangle, then the area = (12 x 7) = 84 square feet = 9 and 1/3 square yards

Well, honey, to find the area of a rectangle, you just multiply the length by the width. So for a rectangle that's 7 cm long and 3 cm wide, the area would be 21 square centimeters. It's as simple as that, darling.
