The area of the small shape is 35 square feet. The big shape is larger by a scale factor of 4/3. Find the area of the large shap
sdas [7]

Answer:

Option a) 62.2 square feet  

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the large shape

y ----> the area of the small shape

so

z^{2}=\frac{x}{y}

we have

z=\frac{4}{3}

y=35\ ft^2

substitute

(\frac{4}{3})^{2}=\frac{x}{35}

\frac{16}{9}=\frac{x}{35}

solve for x

x=\frac{16}{9}(35)=62.2\ ft^2

dlinn [17]

Answer:

Step-by-step explanation:

Ratio is an expression that shows the relationship between two items in terms of quantity. It shows how much of one item can be found in another.

Simon used 3 pears and 9 apples to make a fruit salad.

This is expressed in terms of quantity.

The ratio of the number of pears which simon used to the number of apples which simon used will be

Number of pears which simon used ÷ the number of apples which simon used.

The ratio is 3/9.

Simplifying further to its lowest term,

It becomes 1/3

This is done by dividing the numerator and denominator by 3
