\textsf{Rectangle A}

\implies \mathsf {Area = 3 \times 6 = 18cm^{2}}

\implies \bf {Yes}

\textsf {Rectangle B}

\implies \mathsf {Area = 2 \times 9 = 18cm^{2}}

\implies \bf {Yes}

\textsf {Rectangle C}

\implies \mathsf {Area = 5 \times 4 = 20cm^{2}}

\textsf {Rectangle D}

\implies \mathsf {Area = 9 \times 2 = 18cm^{2}}

\implies \bf {Yes}

Step-by-step explanation:

Let's solve one by one in order to get which has an area of 18cm²

We know that,

  • Ar(Rectangle) = l*b

We'll use this formulae.

Rectangle A:

  • l*b
  • (6*3)cm²
  • 18 cm²

Rectangle B:

  • l*b
  • (9*2)cm²
  • 18 cm²

Rectangle C:

  • l*b
  • (5*4)cm²
  • 20 cm²

Rectangle D:

  • l*b
  • (9*2)cm²
  • 18 cm²

Hence, Rectangle A,B and D Has an area of 18cm².

Answer:

The center is (20, 0.05)   radius = 9

Step-by-step explanation:

The center is (20, 0.05)   radius = 9

from the general form of the equation:

(x - h)^2 + (y - k)^2 = r^2

we see that  r^2 = 81

so r = 9
