Geometry (1)( Week 7 Practice) 1. The length of a rectangle is 7 less than twice the width. If the perimeter is 106 feet, what is the area (in square feet)? 2. A quadrilateral is a polygon with four sides. A trapezoid is a quadrilateral with only one pair of parallel sides. A parallelogram is a quadrilateral with two pairs of parallel sides. A rectangle is a quadrilateral with four right angles. A rhombus is a quadrilateral with four sides of equal length.

The base of a triangle is 2.2 inches and its height is 1.2 inches. If a vertical line is drawn from the top to the base, the line intersects the base 1 inches from one corner and forms two new triangles. What is the area difference (in square inches) of the two new triangles? 5. There are two equal sides in a triangle ABC. ∠A = 120°, what is ∠B in degrees? |
