Explain how to find the area of the composite figure below. Be as specific as possible, using the formulas provided. [A=bh, A=lw, A=1/2bh, A=1/2h(b1+b2)]. PLEASE HELP!

60m

Step-by-step explanation:

4×6=24 so you have that first chunk of the left side.

since 12-4= 8 you can tell that the bottom of the "triangle" is 8m

3x8÷2=12 so now youhave one part left.

since we have already inferred that the base of the triangle was 8m we know that the length of the rectangle was 8m. 8×3=24

now you add the three values. 24+12+24=60

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

you'll have to attache the image of the bar graph in order for us to answer : )
