Engage ny eureka math 5th grade module 5 lesson 10 answer key, eureka math grade 5 module 5 lesson 10 problem set answer key.
Sketch the rectangles and your tiling. Write the dimensions and the units you counted in the blanks. Then, use multiplication to confirm the area. Show your work. We will do Rectangles A and B together. Question 1. Rectangle A: Rectangle A is
________ units long _________ units wide Area = ________ units 2 Answer:
3 units long 2 units wide Area = 6 units 2
Question 2. Rectangle B: Rectangle B is ________ units long _________ units wide Area = ________ units 2 Answer:
3 units long 2 1/2 units wide Area = 7 1/2 units 2
Question 3.
Rectangle C: Rectangle C is ________ units long _________ units wide Area = ________ units 2 Answer:
5 units long 1 1/2 units wide Area = 7 1/2 units 2
Question 4. Rectangle D: Rectangle D is ________ units long _________ units wide Area = ________ units 2 Answer:
2 units long 1 3/4 units wide Area = 3 1/2 units 2
Question 5. Rectangle E: Rectangle A is ________ units long _________ units wide Area = ________ units 2 Answer:
5 units long 3/4 units wide Area = 3 3/4 units 2
Given, the measurement of side = 2 1/4
Area = 2 1/4 x 2 1/4
= 5 1/16 square inches
Total number of squares = 12
Now, 12 x 5 1/16
= 60 3/4 sq. inches
I counted the number of squars and multiplied with the area
Therefore, total area = 60 3/4 square inches
Question 7. A rectangle has a perimeter of 35\(\frac{1}{2}\) feet. If the length is 12 feet, what is the area of the rectangle? Answer:
Given, the perimeter of rectangle = 35 1/2 feet
length = 12 feet
Now, 35 1/2 – 12
= 11 1/2 feet
11 1/2 / 2 = 5 3/4 feet
So, area = 5 3/4 x 12
= 60 + 36/4
= 69 sq. feet
Therefore, the area of the rectangle = 69 sq. feet.

2 1/4 units long 4 units wide Area = 9 units 2
c. Rectangle C: Rectangle C is ________ units long _________ units wide Area = ________ units 2
3/4 units long 4 units wide Area = 3 units 2
d. Rectangle D: Rectangle D is ________ units long _________ units wide Area = ________ units 2 Answer:
Question 2. Rachel made a mosaic from different color rectangular tiles. Three tiles measured 3\(\frac{1}{2}\) inches × 3 inches. Six tiles measured 4 inches × 3\(\frac{1}{4}\) inches. What is the area of the whole mosaic in square inches? Answer:
1. The number of tiles = 3
Measurement = 3 1/2 x 3
= 9 + 1 1/2 = 10 1/2
Now, 3 x 10 1/2 = 31 1/2 sq. inches
Given, number of tiles = 6
Measurement = 4 x 3 1/4
Now, 6 x 13 =48 sq inches
The whole area of mosaic = 31 1/2 + 48
Therefore, total area = 79 1/2 square inches
Question 3. A garden box has a perimeter of 27\(\frac{1}{2}\) feet. If the length is 9 feet, what is the area of the garden box? Answer:
Given, the perimeter of garden box = 27 1/2
the length = 9 feet
27 1/2 – 18 = 9 1/2
9 1/2 / 2 = 9 1/2 x 1/2
19/2 x 1/2 = 19/4 = 4 3/4
Area = 9 x 4 3/4 = 36 + 27 / 4
= 36 +6 3/4
Therefore, total area of garden is 42 3/4 .
