The width of a rectangle is one half its length. The perimeter of the rectangle is 54 cm. What are the width and length of the

lord [1]

Answer:

Length of rectangle = 18 cm

Width of rectangle = 9 cm

Step-by-step explanation:

Let the length of rectangle be x

$\therefore \: width \: (w) = \frac{1}{2} x \\ \\ perimeter \: of \: rectangle = 54 \: cm \\ \therefore \:2(l + w) = 54 \\ \therefore \:(l + w) = \frac{54}{2} \\ \therefore \:l + w= 27 \\ \\ \therefore \:x + \frac{1}{2} x = 27 \\ \\ \therefore \:\frac{3}{2} x = 27 \\ \\ \therefore \:x = 27 \times \frac{2}{3} \\ \\ \therefore \:x = 9 \times 2 \\ \\ \huge \red{ \boxed{\therefore \:x = 18}} \\ \\ \implies \: \frac{1}{2} x = \frac{1}{2} \times 18 = 9$

Hence

Length of rectangle = 18 cm

Width of rectangle = 9 cm

Find the nth term of this quadratic sequence 4 9 16 25 36

TEA [102]

Answer:

Step-by-step explanation:

a₁ = 4 = 2² = (1 + 1)²

a₂ = 9 = 3² = (2 + 1)²

a₃ = 16 = 4² = (3 + 1)²

a₄ = 25 = 5² = (4 + 1)²

a₅ = 36 = 6² = (5 + 1)²

Therefore:

<u>aₙ = (n + 1)² = n² + 2n + 1</u>
