A team is excavating an archeological site. The original plan was to excavate a rectangular area 35 ft long
nikitadnepr [17]

Answer:

Part 1) The length of the new rectangle is 87.5\ ft

Part 2) The area of the new rectangle is 4,375\ ft^{2}

Step-by-step explanation:

we know that

If two rectangles are similar, then the ratio of its corresponding sides is proportional

step 1

Find the length of the new rectangle

Let

L-----> the length of the new rectangle

\frac{50}{20}=\frac{L}{35}\\ \\ L=50*35/20\\ \\L=87.5\ ft

step 2

Find the area of the new rectangle

we know that

The area of the rectangle is

A=LW

we have

L=87.5\ ft

W=50\ ft

substitute

A=(87.5)(50)=4,375\ ft^{2}
