Kareem Brennan · Answer 1

60.5*46.5=2813.25

60.5*0.7=42.35

46.5*0.7=32.55

42.35*32.55=1378.4925

2813.25-1378.4925=1434.7575

Answer = 1435 square feet

Lizzy · Answer 2

Current house area = 60.5 * 46.5 = 2,813.25 square feet

Smaller House Measures 60.5*.7 (42.35) by 46.5*.7 (32.55)

Smaller House area = 42.35 * 32.55 = 1,378.50 square feet

Difference in square feet = 2,813.25 - 1,378.50 equals

1,434.75 square feet
