Answer:

Square.

Explanation:

The surface formulae for a rectangle and a square are, respectively:

A_{r} = w\cdot h

A_{s} = l^{2}

The surfaces are computed herein:

A_{r} = (7\,in)\cdot \left(\frac{3}{4}\,in\right)

A_{r} = \frac{21}{4}\,in^{2}

A_{s} = \left(\frac{5}{2}\,in\right)^{2}

A_{s} = \frac{25}{4}\,in^{2}

Since A_{s} > A_{r}, the square has the largest area.

What is the difference in uniformity between heterogeneous and homogeneous mixtures?
Aneli [31]

Answer:

The correct answer according to the uniformity the difference is whether you can distinguish more than one part in the mixture.

Explanation:

A homogeneous mixture is one in which with the naked eye or with a microscope no different parts can be distinguished. Its composition and properties are the same at all points, the substance is uniform.

In a heterogeneous mixture, we can observe different parts. Its composition is variable.  It can be broken down into simpler substances by physical processes. The substance, in this case, is not uniform.

Have a nice day!
