What is the area of this?
Vanyuwa [196]

area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2}

area =  \frac{1}{2} bh \\ area =  \frac{1}{2} (6)(4) \\ area =  \frac{1}{2} (24) \\ area = 12 {feet}^{2}

total area = 45 + 12

total area = 57 feet²

What value should go in the empty box to complete the calculation for finding the product of 62.834 × 0.45? A)2,213,360 B)2,313,
Aleonysh [2.5K]

Answer:

28.27530

Step-by-step explanation:

Given the expression 62.834 × 0.45, to solve this expression, first we need to convert it to fraction

62.834 = 62834/1000

0.45 = 45/100

Take the product if the resulting fraction:

62.834 × 0.45 = 62834/1000 × 45/100

= (62834×45)/1000×100

= 2,827,530/100,000

= 28.27530
