A rectangular piece of card has a perimeter of 40cm and width of 8cm.
1 answer:
Answer:
Area of the rectangular piece of card = 96 sq.cm
Step-by-step explanation:
here we go,
peremeter ( p ) = 2 × ( length (L) + width (B) )
so,
=》40 = 2 ( L + 8 )
=》40 / 2 = L + 8
=》20 = L + 8
=》L = 20 - 8
=》L = 12
so, length of the card = 12cm
now,
Area (A) = length (L) × width (B)
=》A = 12 × 8
=》Area = 96 sq.cm

Answer:
f(15) = 242
Step-by-step explanation:
Step 1: Define
f(x) = 2(4 - x)²
f(15) = x = 15
Step 2: Substitute and Evaluate
f(15) = 2(4 - 15)²
f(15) = 2(-11)²
f(15) = 2(121)
f(15) = 242
