The area of a rectangular mirror is 15 7 16 square feet. The width of the mirror is 3 1 4 feet. If there is a 5 foot tall space

Vlad1618 [11]

Given:

Area of rectangle = $15\dfrac{7}{16}$ sq. feet.

Width of the mirror = $3\dfrac{1}{4}$ feet.

To find:

Whether it will fit on the wall whose length is 5 foot.

Solution:

We know that, area of a rectangle is

$Area=length\times width$

$\dfrac{Area}{width}=length$

Substituting the given values, we get

$Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}$

$Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}$

$Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}$

$Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}$

$Length=\dfrac{247}{16}\times \dfrac{4}{13}$

$Length=4.75
$

So, length of mirror is 4.75 feet which is less than 5 feet.

Therefore, the mirror will fit on the wall.
