6.3/6.4 HW Flashcard

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If the length of a rectangle is 12 and the width is 5, what is the area?

Back

Area = 12 × 5 = 60.

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

How do you find the missing side of a rectangle if you know the area?

Back

Divide the area by the known side length.

Front

If a rectangle has an area of 48 and a width of 6, what is the length?

Back

Length = Area ÷ Width = 48 ÷ 6 = 8.

Front

What is the relationship between the opposite angles of a parallelogram?

Back

The opposite angles of a parallelogram are equal.

Front

If one angle of a parallelogram is 70 degrees, what are the measures of the other angles?

Back

The opposite angle is also 70 degrees, and the adjacent angles are 110 degrees each.

Front

What is the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

If a rectangle has a length of 10 and a width of 4, what is the perimeter?

Back

Perimeter = 2 × (10 + 4) = 28.

Front

What is the sum of the interior angles of a parallelogram?

Back

The sum of the interior angles of a parallelogram is 360 degrees.
