Step-by-step explanation:
area of first figure=444
area of second figure=57
area of third figure=132
Explanation
The first figure
has 9 faces, 2 triangular and 7 rectangular.
bottom face-rectangle
length=16
breadth=5
area=l*b=16*5=80(1)
two similar rectangular faces
length=16
breadth=4
area=l*b=16*4=64
area of two faces=2*64=128(2)
two similar rectangular faces
length=5
breadth=4
area=5*4=20
area of two faces=2*20=40(3)
two top slant faces-rectangular
length=10
breadth=5
area=10*5=50
area of two faces=2*50=100(4)
two triangular top faces
base=16
height=6
area=1/2 bh=1/2 *16*6=48
area of two faces=2*48=96(5)
total area of the structure=(1)+(2)+(3)+(4)+(5)=80+128+40+100+96=444
The second figure
It has two triangles
triangle 1
length=7
breadth=3
area1=l*b=21
triangle 2
length=9
breadth=4
area2=l*b=9*4=36
total area=area1+area2=21+36=57
<u>T</u><u>he third figure </u>
It has a rectangle and triangle
r<u>ectangle</u>
length=20
breadth=6
area1=l*b=20*6=120
triangle
base=20-(8+6)=20-14=6
height=10-6=4
area2=1/2 bh=1/2*6*4=12
total area=area1+area2=120+12=132
Answer:
Step-by-step explanation:
Im not sure about the first two about fraction bars, a fraction bar looks like this 1/10 or 4/9, maybe the question is asking you to make a fraction of each side so that they both equal the same thing using common denominators.
In that case #2 would be 21/3= 21/7
still not sure about #1
X+32=40
subtract 32 on each side
x+32-32=40-32
x=8
At a restaurant, Mike and his three friends decided to divide the bill evenly. If the total bill was $51.24, how much did each person pay?
Write and solve an equation for the above situation. Use "b" as the variable
4b=51.24
divide each side by 4
4b/4= 51.24/4
b=12.81
Each friend spent $12.81 on the bill.
How many packages of diapers can you buy with $40 if one package costs $8?
Write and solve an equation for the above situation. Use "p" as the variable
8p=40
divide each side by 8
8p/8=40/8
p=5
You can buy 5 packages of diapers with $40
Y=7x+10
He needs to go to the movies 11 times to get a free ticket
Hope this helps
