How many square feet of outdoor carpet will we need for this hole?

I assume the hole is the green part.

It's a 12×4 rectangle with a 3×2 rectangle and a 1×2 rectangle removed.

Area = 12(4) - 3(2) - 1(2) = 48 - 6 - 2 = 40

40 square 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.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
