Question

Find the area and perimeter of the composite shape below... WILL GIVE BRAINLIST FOR BEST ANSWER !!!

Answer 1

Step-by-step explanation:

The perimeter of a shape is all the outside measurements of its sides rogether. So, add all the sides.

$3 + 3 + 2 + 3 + 3 + 3+ 10 + 3 + 3 + 6 \\ = 39$

So 39 is your perimeter.

As for the area, you could do this in many ways since this shape can be cut up into all sorts of smaller shapes, but I'm assuming you mean surface area. To get that, take the area of all the shapes there are in this one and then add them all together. I added an attachment of the areas I'm going to take. I separated the shape into three different ones.

These are all rectangles, and the area for a rectangle is lw.

So...

$lw + lw + lw$

^This will be the formula to use for the area. Keep in mind, these are all different areas separately, so you do not combine the like terms (as tempting as it may be).

Now just substitute: 3×3 3×5 3×10

$(3 \times 3) + (5 \times 3) + (10 \times 3) \\ 9 + 15 + 30 \\ 54$

So 54 is your area.

Answers:

$39cm$

$54{cm}^{2}$

Answer 2

Perimeter:

3+3+2+3+10+3+3+6+2+3=38

Perimeter is 38

Area:

Shape a: 3*3=9

Shape b: 3*5=15

Shape c: 10*3=30

30+15+9=54

Area is 54
