A. Mixture and D. Compound
Isabella has a pool that has an area of 678.32 dam² while Taddeo has one of 865.42 m². Which pool has the largest surface area?
Solution :
We know, 1 dam² = 100 m².
So, area of Isabella pool in m² is :
A = 678.32 × 100 m² = 67832 m² .
Therefore, area of Isabella is greater that volume of Taddeo .
