a. Chocolate need to cover a rectangle with a length of 9 in. and a perimeter of 22 inches is 18 pieces of 1 inch square piece chocolates
b.Chocolate need to cover a rectangle with a length of 5 in. and a perimeter of 20 inches is 20 pieces of 1 inch square piece chocolates
Step-by-step explanation
a. To cover a rectangle with a length of 9 in. and a perimeter of 22 in.
perimeter = 2(length+breadth)
Breadth = 22 -9×2 = 22-18 = 4 ÷ 2 = 2 inches
Area of rectangle = 9 × 2 = 18 inches
18 pieces of 1 inch square piece Chocolate is needed to cover the rectangle
b. To cover a rectangle with a length of 5 in. and a perimeter of 20 in.
perimeter = 2(length+breadth)
Breadth = 20 - 5 ×2 = 10 = 10 ÷ 2 = 5 inches
Area of rectangle = 5 × 5 = 20 inches
20 pieces of 1 inch square piece Chocolate is needed to cover the rectangle
Answer:
P = 2x + 2y + 14
Step-by-step explanation:
Length (L) = x + 8 units
Width (W) = y - 1 units
Perimeter (P) = 2L + 2W
P = 2(x + 8) + 2(y - 1)
P = 2x + 16 + 2y - 2
P = 2x + 2y + 16 - 2
P = 2x +2y + 14
