What is the length of a rectangle with an area of 8 1/10 square feet and a width of 2 1/4 feet?
Leviafan [203]

Answer:

3 6/10 square feet

Step-by-step explanation:

The area of the rectangle is 8 1/10

The width of the rectangle is 2 1/4

We are required to find the length

Area= length × width

Length= Area/width

= 81/10 / 9/4

= 81/10 × 4/9

= 36/10

= 3 6/10

Hence the length of the rectangle is 3 6/10 square feet

6 2/3 times 2 plus 3 1/5 times 2
kramer

Answer:

19\frac{11}{15}

Step-by-step explanation:

We have the problem:

6\frac{2}{3} *2+3\frac{1}{5} *2

6 2/3 can be written as (6 + 2/3), and 3 1/5 can be written as (3 + 1/5). So, we can then use the distributive property:

(6+2/3)*2+(3+1/5)*2=12+4/3+6+2/5=18+4/3+2/5

Now, we need to combine the fractions by finding a common denominator. Here, the common denominator is 3 * 5 = 15: 4/3 +2/5=20/15+6/15=26/15=1\frac{11}{15}

Finally, we add 18 to 1 11/15: 18+1\frac{11}{15} =19\frac{11}{15}

Thus, the answer is 19\frac{11}{15}.

Hope this helps!
