### Instruction:
Jason is making sand art. He wants to fill a rectangular patch 6 inches by 7 inches with blue sand, and a square path 5 inches by 5 inches with red sand. If it takes 3 grams of sand to fill one square inch, how many grams of sand does Jason need?

### Response:
 Eneo lenye umbo la pembetatu lina 6 * 7 = <<6*7=42>>42 inchi za mraba.
Eneo lenye umbo la mraba lina 5 * 5 = <<5*5=25>>25 inchi za mraba.
Jumla ya idadi ya inchi za mraba ni 42 + 25 = <<42+25=67>>67 inchi za mraba.
Jumla ya idadi ya gramu za mchanga ni 67 * 3 = <<67*3=201>>201 gramu.
