Answer:
132 ft²
Step-by-step explanation:
If you combine the two triangles of the 'roof', you get a rectangle of 6x5.5=33, where 6 is calculated as 15-9 and 5.5 comes from 11/2.
Add to that the area of the rest of the 'house', which is a rectangle of 9x11=99
and the total area is 63+99 = 132.
133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
6f = x
x stands for how many flowers the parade can use
C , it’s become more adapted to and more modern
Answer:
lateral surface area = 48 inches²
Step-by-step explanation:
The picture below is the square base pyramid you are referring. The lateral area is adding the area of the 4 triangles in the pyramid.
area of a triangle = 1/2 × b × h
The slant height of the triangle is gotten using Pythagoras theorem
lateral surface area = 4 × (1/2 × 3 × 8)
lateral surface area = 4 × 24/2
lateral surface area = 4 × 12
lateral surface area = 48 inches²
