### Instruction:
 Mstatili una urefu wa mita 40 na upana wa mita 20. Mstatili mdogo unaofanana una nusu ya urefu na upana wa mstatili mkubwa. Ni eneo gani la mstatili mdogo?


### Response:
 Mstatili mdogo una nusu ya urefu wa mstatili mkubwa, ambao ni mita 40/2 = <<40/2=20>>20. Pia una nusu ya upana wa mstatili mkubwa, ambao ni mita 20/2 = <<20/2=10>>10. Hivyo, eneo la mstatili mdogo ni 20 * 10 = <<20*10=200>>200 mita za mraba.
