Question

A rectangle has one side that measures 10 units and another side that measures 4 units.Circle the two measurement units that show the length and width of another rectangle with the same perimeter.

4 units 5units

8 units 3 units

9units 7 units

Answer 1

None of the above

Explanation:

10 + 10 + 4 + 4 = 28

First choice

4 + 4 + 5 + 5 = 18 X

Second choice

8 + 8 + 3 + 3 = 22 X

Third choice

9 + 9 + 7 + 7 = 32 X

Therefore there is none that are the same.

Answer 2

None of the above.

Explanation:

A rectangle has one side that measures = 10 units

the another side that measures = 4 units

Perimeter = 2( Length + width )

Perimeter of this rectangle = 2( 10 + 4 )

= 2(14) = 28 units

We have to find the same measurement units that shows the same perimeter.

1. 4 units 5 units

Perimeter = 2( 4 + 5 ) = 2 × 9 = 18 units

2. 8 units 3 units

Perimeter = 2( 8 + 3 ) = 2 × 11 = 22 units

3. 9 units 7 units

Perimeter = 2( 9 + 7 ) = 2 × 16 = 32 units

There are no another rectangle with the same perimeter.
