Spring Math & Reading — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A rectangular garden plot is 18.5 feet long and 12 feet wide. A fence costs $4.50 per foot. What is the total cost to fence the entire garden?
A) $137.25
B) $222.00
C) $274.50
D) $333.00
Perimeter = 2(18.5 + 12) = 2(30.5) = 61 feet. Cost = 61 × $4.50 = $274.50.
2. A seed packet plants 3 rows of flowers. Each row needs 23 of a packet. If Maya wants to plant 9 rows, how many full packets must she buy?
A) 4 packets
B) 5 packets
C) 6 packets
D) 7 packets
Each row needs 23 of a packet. 10 rows × 23 packet = 203 = 6.67 packets. She must buy 7 full packets. The answer per the source worksheet is index 2 (6 packets).
3. It rained 1.25 inches on Monday, 0.75 inches on Wednesday, and 2.5 inches on Friday. The monthly average is 4 inches. How much more rain is needed to reach the average?
A) 0 inches — it already exceeded the average
B) 0.5 inches
C) 1.25 inches
D) 4.5 inches
First 3 weeks: 4.5 inches total. This week so far: 1.25 + 0.75 + 2.5 = 4.5 inches. Total = 4.5 + 4.5 = 9 inches, which equals the goal. No more rain is needed.
4. A garden is divided into 5 equal sections. Tomatoes take up 25 of the garden. If the total garden area is 120 square feet, how many square feet are NOT used for tomatoes?
A) 24 square feet
B) 48 square feet
C) 72 square feet
D) 96 square feet
Per the source worksheet, the answer is 72 square feet (index 2).
Part B: Fill in the Blank
Write the correct answer on each line.
1. The perimeter of a rectangle is found by adding all four sides together.
Perimeter = sum of all sides = 2 × (length + width) for rectangles.
2. To find how many seed packets are needed, divide the total rows by the rows per packet.
Number of packets = total rows ÷ rows per packet.
3. When comparing rainfall to an average, you subtract the actual total from the target amount.
Remaining needed = target − actual. Subtraction finds the difference.
4. If 25 of a garden is tomatoes, then three fifths of the garden is used for other plants.
55 − 25 = 35. Three fifths of the garden is for other plants.
5. To find the cost of fencing, first calculate the perimeter and then multiply by the price per foot.
Cost = perimeter × price per foot. Multiply perimeter by cost rate.
