Area Builder Level 1 Level 2 Investigation Description Help Video More Measures

This is level 2: find the dimensions of rectangles given their areas and perimeters. You can earn a trophy if you get at least 7 questions correct and you do this activity online. The diagrams are not drawn to scale.

1. Find the shortest side of a rectangle if its area is 35 square centimetres and its perimeter is 24 centimetres.

Area = 35cm2
Perimeter = 24cm

Working:

cm Correct Wrong

2. Find the shortest side of a rectangle if its area is 72 square centimetres and its perimeter is 36 centimetres.

Area = 72cm2
Perimeter = 36cm

Working:

cm Correct Wrong

3. Find the longest side of a rectangle if its area is 152 square metres and its perimeter is 54 metres.

Area = 152m2
Perimeter = 54m

Working:

m Correct Wrong

4. Find the longest side of a rectangle if its area is 18 square metres and its perimeter is 22 metres.

Area = 18m2
Perimeter = 22m

Working:

m Correct Wrong

5. Find the difference between the lengths of the longest and shortest sides of a rectangle if its area is 1254 square milimetres and its perimeter is 142 milimetres.

Area = 1254mm2
Perimeter = 142mm

Working:

mm Correct Wrong

6. Find the difference between the lengths of the longest and shortest sides of a rectangle if its area is 1312 square milimetres and its perimeter is 146 milimetres.

Area = 1312mm2
Perimeter = 146mm

Working:

mm Correct Wrong

7. A rectangle's length is 5cm longer than its width. Its area is 1476cm². What is it's width?

Working:

cm Correct Wrong

8. A rectangle's width is 5m shorter than its length. Its perimeter is 170m. What is it's length?

Working:

m Correct Wrong

9. The numerical value of the area of a square is 6 times bigger than its perimeter when measured using the centimetres. How long is the side of this square?



SQUARE

Area = 6 × Perimeter

Working:

cm Correct Wrong

10. This last question is about a cuboid. Find the shortest side of a cuboid if its volume is 196 cubic feet and its surface area is 210 square feet. You might also find it helpful to know that the sum of the length of all 12 sides is 72 feet.Cube

Working:

feet Correct Wrong

One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
