19. You Try! Determine between what two numbers each square root falls between√50 √31 √105Check your answers on the calculator

20. 5. Square Root word ProblemsAs part of her art project, Shannon willneed to make a square covered in glitter. Her tube of glitter covers 13 square inches. What is the greatest side length Shannon’s square can have?

21. 1 Understand the problemThe answer will be the side length of the square.List the important information:• The tube of glitter can cover an area of 13 square inches.Square inches=AreaMake a PlanThe side length of the square is because 13.=Because 13 is not a perfectsquare, is not a whole number. Estimateto the nearest whole number.2

22. Because 13 is closer to 16 than to 9, is closer to 4 than to 3. 34Does Shannon have enough for a square that has a side length of 4? What is the answer?
