5th grade STAAR test Math Exam

5th grade STAAR test Math Exam The area of a rectangular garage is 20 square meters. The garage is 5 meters long. How wide is it? - Answer-To solve: Area = Length x width, you have length (5) but not width, and you know the total square meters = 20 so 5 x 4 = 20 Answer: 4 A rectangular picnic area is 100 yards wide and 127 yards long. What is its perimeter? - Answer-To solve: a perimeter is the sum of all sides, if you know width (100) and length (127) then you know the other two sides are equal to their counterpart (100 and 127). Answer: 454 Each side of a square kitchen tile is 3 inches long. What is the tile's area? - Answer-To solve: squares have all equal sides, so 3 inches x 4 = 12 for perimeter, for area it is 3 x 3 or 9. Answer: 9 A square piece of gold has a perimeter of 80 millimeters. How long is each side? - Answer-To solve: squares have all equal sides, so 80 divided by 4. Answer: 20 The area of the surface of a workbook is 54 square inches. The workbook is 6 inches wide. How tall is it? - Answer-To solve: area = length x width. You have L x 6 = 54 (trying to find L or Length). What x 6 = 54? Answer: 9 A rectangle has a length of 3 inches and width of 4 inches. 1 inch in this model is equivalent to 20 feet. How many square feet is the area of the rectangle? - Answer-To solve: you first have to convert the inches to equivalent feet (1 inch is equivalent to 20 feet so 3 x 20, and 4 x 20). Then (and only then) can you multiply to find the area (L x W = Area, or 60 x 80 = 4800 square feet is the area). Answer: 4800 A square has a length of 60 feet and a width of 80 feet. 20 feet = 1 inch. How many square inches is the area of the square? - Answer-You have to divide (20 feet = 1 inches, so 60 divided by 20, and 80 divided by 20) first. Then and only then can you multiple length times width to get the area. Answer: 12 .97 x 100 = ? Continues...
