Math in Focus Grade 4 Chapter 12 Practice 4 Answer Key Composite Figures

Find the lengths of the unknown sides of each figure. Then find the perimeter of each figure.

Example

Length of first unknown side = 16 – 4 = 12 in.
Length of second unknown side = 13 + 4 = 17 in.
Perimeter of figure = 16 + 13 + 12 + 4 + 4 + 17 = 66 in.
Perimeter = 66 in.

Question 1.

Perimeter = ____________ yd
Answer:

Length of first unknown side = 6 yards
Length of second unknown side = 24 yards – 8 yards – 5 yards = 11 yards
Perimeter of figure = 5 yd + 6 yd + 8 yd + 3 yd + 24 yd + 3 yd + 11 yd +6 yd
= 66 yd
Perimeter = 66 yd.

Solve. Show your work.

Question 2.
Tom wants to fence in the piece of land shown in the diagram. Find the perimeter of the piece of land to find the length of fencing material he needs.

Perimeter = __________ m
Answer:
Length of first unknown side = 8 m
Length of second unknown side = 9 m
Length of third unknown side = 3m
Perimeter of the piece of land = 3 m + 8 m + 12 m + 8 m + 9 m + 3 m + 3 m = 46 m
Perimeter = 46 m
He needs 46 m of fencing material.

Question 3.
Find the perimeter of this figure.

Perimeter = ___________ mi
Answer:

Length of first unknown side ST = 28 mi – 12 mi = 16 mi
Length of second unknown side TU = 24 mi – 6 mi = 18 mi
Perimeter of the figure = 28 mi + 6 mi + 16 mi + 18 mi + 12 mi + 24 mi = 104 mi
Perimeter = 104 mi

Solve. Show your work.

Question 4.
Find the perimeter of the figure.

Perimeter = ___________ cm
Answer:
Perimeter  of the figure = 42 cm + 18 cm + 34 cm + 42 cm + 16 cm = 152 cm
Perimeter = 152  cm

Find the area of each composite figure. Show your work.

Example

Break up the figure into two rectangles as shown. Then find the area of the whole figure.

Area of rectangle 1 = length × width
= 10 × 3
= 30 in.²
Area of rectangle 2 = length × width
= 7 × 6
= 42 in.²
Total area = area of rectangle 1 + area of rectangle 2
= 30 + 42
= 72 in.²
Area = 72 in.²

Find the area of each composite figure. Show your work.

Question 5.

Area = ____________ ft²
Answer:
For rectangle 1
length = 22 feet
Width = 18 feet
Area of rectangle 1 = length × width
= 22 feet × 18 feet
= 396 ft²
For rectangle 2
length = 14 feet
width = 9 feet
Area of rectangle 2 = length × width
= 14 feet × 9 feet
= 126 ft²
Total area = area of rectangle 1 + area of rectangle 2
= 396 ft²+ 126 ft²
= 522 ft²
Area =522 ft²

Question 6.

Area = __________ m²
Answer:

Explanation:
For rectangle 1
length = 12 m
Width = 5 m
Area of rectangle 1 = length × width
= 12 m × 5 m
= 60 m²
For rectangle 2
length = 8 m
width = 3 m
Area of rectangle 2 = length × width
= 8 m × 3 m
= 24 m²
Total area = area of rectangle 1 + area of rectangle 2
= 60 m²+ 24 m²
=84 m²
Area =84 m²
