42 - 47

Polygons are

triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram

The area of triangles = 1/2 * base * haight.

Area of the parallelograms = height * base.

Area of rectangle= width * length

Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides

The perimeters = sum of the sides of the polygons.

Find the area of a parallelogram whose base is 12cm and altitude is 8cm. Also find the other base of its corresponding altitude
lukranit [14]

Answer:

Step-by-step explanation:

Area of parallelogram = base * height

                                    = 12 * 8

                                    = 96 cm²

Area of parallelogram = 96

base * height = 96

          base = 96/height

          base = 96/16

         base = 6 cm

Write a proportion that can be used to find the cost of 10 notebooks if 3 notebooks cost $1.98.
Mariulka [41]
The solution to the problem is as follows:


For 3 notebooks you pay $1.98 so the ratio is 1:0.66.
For 10 notebooks, then we could scale the ratio and it will become 10:6.60. So they will cost you $6.60.
