a rectangle has an area of 50 centimeters squared. The dimensions of the rectangle are multiplied to form a new rectangle with an area of 200 centimeters squared. by what number were the dimensions multiplied?

2

Step-by-step explanation:

Let A₁ = the original area a

and A₂ = the new area

and n = the number by which the dimensions were multiplied

A₁ = lw

A₂ = nl * nw = n²lw

A₂/A₁ = (n²lw) / (lw) = 200/50

n² = 4

n = 2

The dimensions were multiplied by a factor of 2.
