Arectangle has an area of 7.1m2(squared). one of the sides is 0.1m in length. work out the perimeter of the rectangle.

L = length = unknown

W = width = 0.1 meters

A = area = 7.1 square meters

Use the formula for an area of a rectangle. Isolate L

A = L*W

7.1 = L*0.1

0.1*L = 7.1

L = 7.1/0.1

L = 71

The rectangle has a length of 71 meters and a width of 0.1 meters (which multiply to an area of 7.1 square meters)

Now use the perimeter formula

P = 2*(L+W)

P = 2*(71+0.1)

P = 2*71.1

P = 142.2

Or you can add up the four sides 71, 71, 0.1, 0.1 and you'll get the same answer.

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.
