Row 1, Col 1 A square has sides of 5 centimeters. If the sides of the square are tripled, what is the area of the new (larger) square? 225 cm²

1,2 Evaluate (0.3)² + (0.5)².34

1,3 In calculating the perimeter of a trapezoid, Aurora measured sides of 14.5 cm, 23cm, 11cm, and 18⅔ cm. (Type the question for 1,3 here.)?

1,4 If the length and width of a rectangle are each multiplied by 5, what will be the effect on its perimeter? The perimeter will be multiplied by 5

2,1 Carlos has a tool shed built in the shape of a trapezoid. To plan the best use of the shed, he needs to know the area of the floor. What formula can be used to find the area of the floor of the shed? 20 ½(b+b)(h) or ½(20+30)(5)

2,2 In the expression below, which operation is performed first? -⅔ + ⅝ ÷ ⅓ ∙ ⅛ - ½ ⅝÷⅓

2,3 What is the approximate circumference of circle C? (use ∏ ≈ 22/7) 56 cm 9

2,4 If the length of each side of a triangle is doubled, then its perimeter is __________________ Doubled or multiplied by 2

3,1 Sam has a sail boat with a large triangular sail that is 14 feet high. And 8 feet wide. What is the area of the sail in square feet? 56 ft²

3,2 Simplify: 2 + 4(x + 6) 4x + 26

3,3 The lengths of the sides of a quadrilateral are given as shown. Express the perimeter in terms of x. X+3 5x+6 X+1 X-2 2x+4

3,4 If each side of a square is tripled, the area of the square is ________________ Multiplied by 9

4,1 What is the base of a triangle with an area of 36 square centimeters and a height of 9 centimeters? 8 cm

4,2 A yardstick is held straight up with one end touching the ground. The shadow of the yardstick is 9 feet long, while the shadow of a nearby flagpole is 135 feet long. What is the height of the flagpole? 45 ft.

4,3 From the ground to the center of a automobile tire is about 30cm. What is a close approximation of the circumference of the tire? cm

4,4 A square has sides of 4 centimeters. If The sides of the square are quadrupled, What is a the area of the new (larger) square? 64 cm²

5,1 John has to paint a rectangular brick wall that is 12 feet long and 8 feet high. However, the wall has a door near the middle that is 7 feet high and 4 feet wide. What is the area of the wall? 68 ft²

5,2 Evaluate: m-n² p³ When m=2, n=3.2, and p=

5,3 A parallelogram has a longer side of 17 inches. If its perimeter is 50 inches, what is the length of the shorter side? 8 inches

5,4 If the three sides of a triangle are each multiplied by 3, what will be the effect on its area? The area will increase 27 times (3x3x3=27)
