a rectangle has an area of 7/8 square units if the width is 7/16 unit what is the length of the rectangle in units?

djyliett [7]

Answer:

$Length=2 units$

Step-by-step explanation:

Given :

Area of the rectangle = $\frac{7}{8}$ square units

Width of the rectangle= $\frac{7}{16}$ units

Area of the rectangle= Length* Width

$\frac{7}{8} =Length*\frac{7}{16}$

Multiplying $\frac{16}{7}$ both the sides

$\frac{7}{8} *\frac{16}{7} =Length$

$Length=\frac{16}{8}$

$Length=2 units$

The length of the rectangle is 2 units
