# Calculate Areas in Metric Measurement: Rectangles

In this worksheet, students calculate the area and perimeter of rectangles using metric measurements.

Key stage:  KS 2

Curriculum topic:   Measurement

Curriculum subtopic:   Calculate/Estimate Areas

Difficulty level:

### QUESTION 1 of 10

Remember that:

The area of a rectangle is it's length x it's width.

The perimeter of a shape is the total distance around it's edge.

All of the problems in this activity are based on these two key facts.

• Question 1

A rectangular field measures 50m by 40m.

What is its area in square metres?

(Just write the number)

2000
EDDIE SAYS
50 x 40 = 2000
• Question 2

A rectangular field measures 50m by 40m.

What is its perimeter in metres?

(Just write the number)

180
EDDIE SAYS
50 + 50 + 40 + 40 = 180
• Question 3

A rectangular field is 40m wide.  It is three times as long as it is wide.

What is its perimeter in metres?

(Just write the number)

320
EDDIE SAYS
40 x 3 = 120 (three times as long as it is wide) 40 + 40 + 120 + 120 = 320
• Question 4

A rectangular field is 40m wide.  It is three times as long as it is wide.

What is its area in square metres?

(Just write the number)

4800
EDDIE SAYS
40 x 120 = 4800
• Question 5

A rectangular field has a perimeter of 100m.  It is 20m wide.

What is its length in metres?

(Just write the number)

30
EDDIE SAYS
The width is 20 + 20 = 40. Subtract the perimeter and the width to get the length 100 - 40 = 60. The length of one side is 60 divided by 2 = 30.
• Question 6

A rectangular field has a perimeter of 100m.  It is 20m wide.

What is its area in square metres?

(Just write the number)

600
EDDIE SAYS
Area = length x width Area = 30 x 20 = 600 (We found the length in the last question. The width is 20 + 20 = 40. Subtract the perimeter and the width to get the length 100 - 40 = 60. The length of one side is 60 divided by 2 = 30.)
• Question 7

A rectangular field has a perimeter of 140m.  It is 20m wide.

What is its area in square metres?

(Just write the number)

1000
EDDIE SAYS
The width is 20 + 20 = 40. Subtract the perimeter and the width to get the length 140 - 40 = 100. The length of one side is 100 divided by 2 = 50. Area = length x width Area = 50 x 20 = 1000
• Question 8

A rectangular field has a perimeter of 150m.  It is 20m wide.

What is its area in square metres?

(Just write the number)

1100
EDDIE SAYS
The width is 20 + 20 = 40. Subtract the perimeter and the width to get the length 150 - 40 = 110. The length of one side is 110 divided by 2 = 55. A = l x w A = 55 x 20 = 1100
• Question 9

A rectangular field has an area of 1600m2.  It is 20m wide.

What is its perimeter in metres?

(Just write the number)

200
EDDIE SAYS
A = length x width 1600 = l x 20 1600/20 = 80 is the length Width = 20 x 2 = 40 Length = 80 x 2 = 160 Perimeter = 160 + 40 = 200
• Question 10

A rectangular field has an area of 1600m2.  It is 50m wide

What is its perimeter in metres?

(Just write the number)

164
EDDIE SAYS
A = l x w 1600 = l x 50 1600/50 = 32 is the length Width = 50 x 2 = 100 Length = 32 x 2 = 64 Perimeter = 100 + 64 = 164
