Solve 1/2*6*4.5+1/2*10*12.5

$$\frac{ 1 }{ 2 } \times 6 \times 4.5+ \frac{ 1 }{ 2 } \times 10 \times 12.5$$

Evaluate

$$76$$

Solution Steps

Multiply \frac{1}{2} and 6 to get \frac{6}{2}.

$$\frac{6}{2}\times 4.5+\frac{1}{2}\times 10\times 12.5$$

Divide 6 by 2 to get 3.

$$3\times 4.5+\frac{1}{2}\times 10\times 12.5$$

Multiply 3 and 4.5 to get 13.5.

$$13.5+\frac{1}{2}\times 10\times 12.5$$

Multiply \frac{1}{2} and 10 to get \frac{10}{2}.

$$13.5+\frac{10}{2}\times 12.5$$

Divide 10 by 2 to get 5.

$$13.5+5\times 12.5$$

Multiply 5 and 12.5 to get 62.5.

$$13.5+62.5$$

Add 13.5 and 62.5 to get 76.

$$76$$

Factor

$$19\times 2^{2}$$
