Find of area of the object

Mathematics
1 answer:
marshall27 [118]2 years ago
6 0

Answer:

140 ft²

Step-by-step explanation:

First, we divide the figure into the two visible polygons. The first being a right angled triangle and the second being a rectangle.

Area of a right angled triangle = <em>0·5 × b × h</em>

= 0·5 × 6 × 4 <em>I've included a picture to show where the 6 and 4 came from</em>

= 12 ft²

Area of a rectangle = <em>l × w</em>

= 16 × 8

= 128 ft²

Add the two areas to get the area of the figure

= 128 + 12

∴ the area of the figure is 140 ft²

Complete the frequency table:
Gala2k [10]

The percentage of students age 15 and above travel to school by bus is 47%

<h3>How to complete the table?</h3>

The table of values is given as:

                     Method of Travel to School

                            Walk/Bike    Bus    Car Row totals

Under age 15                            18                 165

Age 15 and above    65                                 195

Column totals          152          110        98      360

Using the column total of column 1, we have:

Under age 15 + 65 = 152

This gives

Under age 15 = 87

Using the column total of column 2, we have:

Age 15 and above + 18 = 110

This gives

Age 15 and above  = 92

Using the row total of row 1, we have:

Car + 87 + 18 = 165

This gives

Car = 60

Using the row total of row 2, we have:

Car + 65 + 92 = 195

This gives

Car = 38

So, the complete frequency table is

                     Method of Travel to School

                            Walk/Bike    Bus    Car Row totals

Under age 15           87              18      60        165

Age 15 and above    65          92        38        195

Column totals          152          110        98      360

The percentage of students age 15 and above travel to school by bus is:

Percentage = 92/195 * 100%

This gives

Percentage = 47%
