Think of finding each surface area as finding the area of a 2D object
Lets start with the triangle.
area of right triangle = ab/2
6*8=48 48/2= 24
so the triangles surface area is 24, remeber there are 2 identical triangles so multiply 24 by 2 and get 48 again
now lets do one of the rectangles
area of rectangle is ab
so 4*10=40
lets add that to the total
48+40 = 88
Now lets do 8*4= 32
add to total again, 88+32= 120
and now do the last rectangle, 6*4=24
Now get the grand total of it all, 120+24 = 144
Thats how you do it :)
Answer:
Quantity of milk = 60 x 2/3 litres = 40 litres.
Quantity of water in it = (60- 40) litres = 20 litres.
New ratio = 1 : 2
Let quantity of water to be added further be x litres.
Then, milk : water = 40 /20 + x
Now, 40 /20 + x = 1/2
20 + x = 80
x = 60.
Quantity of water to be added = 60 litres.
Answer:
30
Step-by-step explanation:
the answer has to be greater than 6 and less than 36
15+21=36, 21-15=6
Should be 17 degrees F. Just add 22.1 to -5.1.
Area is length x width.
With this one, what we have to do is work out the area of the larger square and the smaller, inside square, and take one from the other.
The larger one is 14 x 14 = 196.
The smaller one is 8 x 8 = 64
So, 196 - 64 = 132m²
