Step-by-step explanation:
The poster is a rectangle.
P = 2 L + 2 W
where L is the length and W is the width of a rectangle.
L = W + 2 1/2 = W + 2.5
103 = 2 ( W + 2.5 ) + 2 W
103 = 2 W + 5 + 2 W
103 = 4 W + 5
4 W = 103 - 5
4 W = 98
W = 98 : 4
W = 24.5 in
L = 24.5 + 2.5
L = 27 in
Answer:
The poster is 27 inches long and 24.5 inches wide.
Remove parentheses; it's the same thing with addition and subtraction.
2+11+y
13+y
2+(11+y) is equivalent to 13 + y.
Area of garden = 81 ft²
Area of square = side²
Perimeter of square = 4 × Side
= 4 × 9
= 36 ft
Fencing needed by Janet = 36 ft
Answer: £180
Step-by-step explanation:
The interest gotten for the 10 years will be calculated as:
= Principal × Rate × Time
= 150 × 2% × 10
= 150 × 0.02 × 10
= 30
The amount he has in the bank account at the end of the 10 year will be:
= Principal + Interest
= £150 + £30
= £180
