Document Summary
Use dimensional analysis to convert 60 miles to meters. Show work: sherice remembers two formulas for rectangles: l x w and 2l + 2w. She doesn"t remember which one gives the area and which gives the perimeter. Use a sketch of a 3-by-4 rectangle to explain which formula is which, and why. Be sure to connect the formulas to the meaning of area and the meaning of perimeter. Also be sure to use the meaning of multiplication to make sense of each formula: find the area of the shaded portion in each shape below. Round final answers to two decimal places as needed: the circle is tangent to both of the bases of the trapezoid below (i. e. , it touches each base in just one point). 30 ft: the outer triangle is equilateral with side length 6 inches. Ad = 8 cm and bc = 6 cm.
