If I have a floor that is 100 3/4 feet by 75 1/2 what is the area

Vlad [161]

The area, assuming is a rectangular floor, is their product.

so simply convert the mixed to improper and get their product.

$\bf \stackrel{mixed}{100\frac{3}{4}}\implies \cfrac{100\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{403}{4}}
\\\\\\
\stackrel{mixed}{75\frac{1}{2}}\implies \cfrac{75\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{151}{2}}\\\\
-------------------------------\\\\
\cfrac{403}{4}\cdot \cfrac{151}{2}\implies \cfrac{403\cdot 151}{4\cdot 2}\implies \cfrac{60853}{8}\implies 7606\frac{5}{8}~ft^2$

The width of a rectangle is 8 inches and the perimeter is 26 inches. What is the length of the rectangle?

fredd [130]

Length of the rectangle is 5 inches

Step-by-step explanation:

Step 1: Perimeter of the rectangle = 26 in and width = 8 in. Find the length.

Perimeter of the rectangle = 2(length + width)

26 = 2(length + 8)

13 = length + 8

length = 13 - 8

Length = 5 in
