Area Builder Level 1 Level 2 Investigation Description Help 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 60 square centimetres and its perimeter is 32 centimetres.

Area = 60cm2
Perimeter = 32cm

Working:

cm Correct Wrong

2. Find the shortest side of a rectangle if its area is 63 square centimetres and its perimeter is 32 centimetres.

Area = 63cm2
Perimeter = 32cm

Working:

cm Correct Wrong

3. Find the longest side of a rectangle if its area is 198 square metres and its perimeter is 58 metres.

Area = 198m2
Perimeter = 58m

Working:

m Correct Wrong

4. Find the longest side of a rectangle if its area is 60 square metres and its perimeter is 32 metres.

Area = 60m2
Perimeter = 32m

Working:

m Correct Wrong

5. Find the difference between the lengths of the longest and shortest sides of a rectangle if its area is 1330 square milimetres and its perimeter is 146 milimetres.

Area = 1330mm2
Perimeter = 146mm

Working:

mm Correct Wrong

6. Find the difference between the lengths of the longest and shortest sides of a rectangle if its area is 1462 square milimetres and its perimeter is 154 milimetres.

Area = 1462mm2
Perimeter = 154mm

Working:

mm Correct Wrong

7. A rectangle's length is 5cm longer than its width. Its area is 864cm². What is it's width?

Working:

cm Correct Wrong

8. A rectangle's width is 4m shorter than its length. Its perimeter is 116m. What is it's length?

Working:

m Correct Wrong

9. The numerical value of the area of a square is 5 times bigger than its perimeter when measured using the centimetres. How long is the side of this square?



SQUARE

Area = 5 × Perimeter

Working:

cm Correct Wrong

10. This last question is about a cuboid. Find the shortest side of a cuboid if its volume is 40 cubic feet and its surface area is 76 square feet. You might also find it helpful to know that the sum of the length of all 12 sides is 44 feet.Cube

Working:

feet Correct Wrong

Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. 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.
