Answer:
144
Step-by-step explanation:
On this shape we are going to splt up the 4 triangles for the square to make it simple.
So, firstly, plug is the h an w of one of the triangles into the formula for the area of a triangle which is hxw/2
H=9
W=6
9x6/2=27
Then multiply the area of the triangle, 27, to get the total area of all 4 triangles (since they all have the same measurements)
27x4=108
108 is the area of all 4 triangles
Next, just put the l and w into the equation for the area of a square which is lxw
L=6
W=6
6x6=36
36 is the area of the square
Lastly, just add the areas of the triangles and the square together
108+36=144
144 is the total area/surface area, of the pyramid
Answer:
Stamp collected in June = 33
Step-by-step explanation:
Total stamp = 94
Stamp collected in April = 27
Stamp collected in May = 34
Stamp collected in June = x
Total stamp = April stamp + May stamp + June stamp
94 = 27 + 34 + x
94 = 61 + x
x = 94 - 61
x = 33
Stamp collected in June = 33
