Mr. chambliss is planning to build a shed with a rectangular floor. in his original plan, the length of the floor was 7 feet and the area of the floor was 35 square feet. in his new plan he wants to extend the length by 3 more feet. if the total area of the shed will be 70 square feet, by how many feet will he have to extend the width?

a. 1 foot
b. 2 feet
c. 3 feet
d. 4 feet

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
