\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.

Law Incorporation [45]

Answer:

The width of the is 4 inches

Step-by-step explanation:

Assume that the width of the frame is x

∵ The width of the fame is x inches

→ That means each dimension will increase by 2x ⇒ x from each side

∵ The portrait has dimensions of 30“ x 60“

∴ Its dimensions including the frame = (30 + 2x) × (60 + 2x)

∴ The total area of the portrait plus frame = (30 + 2x)(60 + 2x)

→ Multiply the brackets

∵ (30 + 2x)(60 + 2x) = 30(60) + 30(2x) + 2x(60) + (2x)(2x)

∴ (30 + 2x)(60 + 2x) = 1800 + 60x + 120x + 4x²

→ Add the like terms

∴ (30 + 2x)(60 + 2x) = 1800 + 180x + 4x²

∴ The total area of the portrait plus frame = 4x² + 180x + 1800

∵ The total area of the portrait plus frame = 2584 square inches

→ Equate the two right sides of the area

∴ 4x² + 180x + 1800 = 2584

→ Subtract 2584 from both sides

∴ 4x² + 180x + 1800 - 2584 = 0

→ Add the like terms in the left side

∴ 4x² + 180x - 784 = 0

→ Divide all terms by 4 to simplify

∴ x² + 45x - 196 = 0

→ Factorize it to find the value of x

∵ x² + 45x - 196 = (x - 4)(x + 49)

→ Equate the right side by 0

∴ (x - 4)(x + 49) = 0

→ Equate each factor by 0

∵ x - 4 = 0  

→ Add 4 to both sides to find x

∴ x = 4

∵ x + 49 = 0

→ Subtract 49 from both sides to find x

∴ x = -49 ⇒ refused it x can not be -ve (no negative dimensions)

∴ The width of the is 4 inches
