Question

Find the perimeter and round your answer to the nearest tenths. Can anyone help me with this? I cannot find any videos or examples like this and I'm extremely confused​

Answer 1

22.8

Explanation:

the rectangular has :

the length CD =√[(3+3)²+(0-5)²]

= √(36+25) = √61 = 7.8

the width BC =√[(5-3)²+(3-0)²]

=√(4+9 =√13 = 3.6

so, the perimeter = 2(7.8 + 3.6)

= 2× 11.4 = 22.8
