Answer:

<h3>28</h3>

Step-by-step explanation:

Area of a square =

s^2

Perimeter =

4\times s

Where s = side

Solve for s using the area

A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7

Find the perimeter

4\times s\\\\= 4 \times 7\\\\= 28

Can someone tell me if I'm right or wrong
dem82 [27]

Step-by-step explanation:

well, it is a combination of 2 shapes.

I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.

that would be

2x2 + 6x5 = 4 + 30 = 34 cm²

but you started a valid approach too.

you "sliced" off a narrow rectangle along the whole right side. 7x2.

and that leaves now a 4x(7-2) rectangle.

so,

7x2 + 4x5 = 14 + 20 = 34 cm²

yes, this was my answer.

how did this suddenly appear as your answer ?
