Question

Natasha's rectangle measures 4 1/2 units by 2 1/4 units. What is its area?

Answer 1

`10(1)/(8)`

Explanation:

→ Multiply the fractions together

`4(1)/(2) *2(1)/(4)`

→ Convert to improper fractions

`(9)/(2) *(9)/(4)`

→ Multiply across

`(81)/(8)`

→ Convert back to mixed number

`10(1)/(8)`

Answer 2

Answer: 49/6units^{2}49/6units

2

Explanation:

You can convert from mixed number to fractions as following:

2 1/3=((2*3)+1)/3=7/3 units

3 1/2=((3*2)+1)/2=7/2 units

Then you can calculate the area of the rectangle as you can see below:

\begin{gathered}Area=lenght*width\\Area=7/2units*7/3units\\Area=49/6units^{2}\end{gathered}

Area=lenght∗width

Area=7/2units∗7/3units

Area=49/6units
