Just remember that
1meter=100 cm
81.66m=81.66*100=8166 cm
Answer:
(14-8)
Step-by-step explanation:
Heres why:
Pedmas
P= Parenthesis
E=Exponents
D=Division
M=Multiplication
A=Addition
S= Subtraction
Do that in order.
35
Area of rectangle
21m^2
Area of one triangle
divide length of 7 by 2 (3.5)
gives you length b (unknown side that is not hypotenuse)
then multiply by width of triangle (4)
3.5 * 4 = 14
and in this situation there is no need to divide by two, because you essentially have one full square from both the triangles. this only works when both triangles are the same.
add the area of the rectangle
14+21= 35
35m^2
