podryga [215]

Answer:

A_{2} = 720\ ft^{2}

Step-by-step explanation:

Let w and l be the width and length of the garage.

Let A_{1} and A_{2} be the area of garage at present and new garage.

Given:

The area of the garage at present

A_{1}=80\ ft^{2}

And he planed to tripling the dimensions of the garage.

We need to find the area of the new garage.

Solution:

We know the area of the rectangular garage.

Area=width\times lendth

A_{1}=w\times l

w\times l=80 ---------------(1)

The dimension of the new garage is triple, so the area of the new garage is.

A_{2} = (3\times width)\times (3\times length)

A_{2} = (3\times w)\times (3\times l)

A_{2} = 9\times (w\times l)

Substitute w\times l=80 from equation 1.

A_{2} = 9\times (80)

A_{2} = 720\ ft^{2}

Therefore, the area of the new garage A_{2} = 720\ ft^{2}
