Octavia o batla go roka kobo ya ga kgaitsadie. O tlile go e roka ka di-T-shirt tse dinnye, tse di magareng le tse dikgolo tse ba malapa a bone ba sa tlholeng ba di dirisa.  T-shirt e nnye ke 3 square feet ya letsela. E e magareng ke 4 square feet. E kgolo ke 6 square feet.  Fa a dirisa di-T-shirt tse dinnye di le 11, tse di magareng di le 8, le tse dikgolo di le 6, kobo eo e tla bo e le bokae ka square feet?

In a family, there are 2 brothers and 3 sisters. All sisters are the same age, which is 16. One of the brothers is 12 years old, which is half the age of the older brother. What is the total age of all these siblings?
Kobo e na le 33 square feet go tswa mo di-T-shirt tse dinnye ka gonne 11 x 3 = <<11*3=33>>33
Kobo e na le 32 square feet go tswa mo di-T-shirt tse di magareng ka gonne 8 x 4 = <<8*4=32>>32
Kobo e na le 36 square feet go tswa mo di-T-shirt tse dikgolo ka gonne 6 x 6 = <<6*6=36>>36
Kobo e 101 square feet ka gonne 33 + 32 + 36 = <<33+32+36=101>>101
#### 101 

Three sisters are in total 3 * 16 = <<3*16=48>>48 years old.
The younger brother is only half the age of the older one, which leads us to the older brother being 12 * 2 = <<12*2=24>>24 years old.
So all family members in total are 48 + 12 + 24 = <<48+12+24=84>>84 years old.
