Respuesta :

[tex]\textsf{Rectangle A}[/tex]

[tex]\implies \mathsf {Area = 3 \times 6 = 18cm^{2}}[/tex]

[tex]\implies \bf {Yes}[/tex]

[tex]\textsf {Rectangle B}[/tex]

[tex]\implies \mathsf {Area = 2 \times 9 = 18cm^{2}}[/tex]

[tex]\implies \bf {Yes}[/tex]

[tex]\textsf {Rectangle C}[/tex]

[tex]\implies \mathsf {Area = 5 \times 4 = 20cm^{2}}[/tex]

[tex]\textsf {Rectangle D}[/tex]

[tex]\implies \mathsf {Area = 9 \times 2 = 18cm^{2}}[/tex]

[tex]\implies \bf {Yes}[/tex]

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.
