Answer 1

224,940

Explanation:

Multiply 230 x 230. Then multiply 230 by 187. Then divide by 1/2. Multiply that answer by 4. Then add the product of 230x230 and 230x187 divided by 2 times 4.

Answer 2

138,920 meters squared. the square is 230×230. the triangles are [1/2(230)(187)] then multiplied by 4 because there are 4 of them. add all together to get 138920.
