Answer:
486 in. & 93 m.
Step-by-step explanation:
a.
The shape shown in part a is a rectangle.
The formula is:
a=b*h
base= 27
height/length= 18
27*18=486
Therefore, the area will be equal to 486 in.
b.
The shape shown in part b is a triangle.
The formula is:
a=1/2b*h
base= 20.75
height=9 (make sure you take the altitude of the triangle, not the slant height)
1/2*20.75*9=93.375
Therefore, the area of the triangle is 93.375 m.
Rounding —> 93 m
