The perimeter of a rectangular table is 20 feet. The width of the table is 3 feet. What is the length of the table
lyudmila [28]

Answer:

7 ft

Step-by-step explanation:

Perimeter of a rectangle is denoted by the formula: P=2l+2w , where l is the length and w is the width.

We know that P = 20 and that w = 3. So, let's plug these values in:

20 = 2l+2*3=2l+6

Isolate the variable l by subtracting 6 from both sides and dividing by 2:

2l=20-6=14

l=7

Thus, the answer is 7 feet.

Hope this helps!

Jessica is a custodian at Oracle Arena. She waxes 20 \text{ m}^220 m 2 20, space, m, start superscript, 2, end superscript of th
Evgesh-ka [11]

Given that Jessica is a custodian at Oracle Arena.

She waxes 20 square meters space of the floor in 5/3 of an hour. Jessica waxes the floor at a constant rate means rate will remain fixed for any hour.

Now we have to find about how many square meters can she wax per hour.

To find that we just need to divide 20 squaer meters by 5/3 hours

\frac{20}{\left(\frac{5}{3}\right)}

=20\cdot\frac{3}{5}

=\frac{60}{5}

=12

Hence final answer is 12 square meters can she wax per hour.

Which can also be written as 12m^2 per hour.
