Perimeter and Area of Quadrilaterals and Triangles9-1 I can find the perimeter of triangles, parallelograms, rectangles, and trapezoids. I can find the area of triangles, parallelograms, rectangles, and trapezoids. I can find missing measurements given the area or perimeter.Review: Special Right Triangles45°30°45°60°**Answers need to be left as simplified radical. Note: Textbook says to round to the nearest tenth… Do not follow these directions! Leave as simplified radical!!`Example Find the perimeter of the rectangle, in which A = (79.8x2 – 42) cm2Step 1 Use the area and the height to find the base.A = bh79.8x2 – 42 = b(21)3.8x2 – 2 = bStep 2 Use the base and the height to find the perimeter.P = 2b + 2hP = 2(3.8x2 – 2)+ 2(21)P = (7.6x2 + 38) cmExample Find the height of a rectangle in which b = 3 in. and A = (6x² + 24x – 6) in2. A = bh6x2 + 24x – 6 = 3h3(2x2 + 8x – 2) = 3h2x2 + 8x – 2 = hh = (2x2 + 8x – 2) in.56 56 Example Find the base of the parallelogram in which h = 56 yd and A = 28 yd2.A = bh28 = b(56) b = 0.5 yd Example Find the base of the triangle, in which A = (15x2) cm2. 6x = bb = 6x cmExample Find b2 of the trapezoid, in which A = 231 mm2.42 = 23 + b219 = b2b2 = 19 mmExample Find the area of the triangle.Find b.A = 96 m2
