Answer:
all three sides are congruent.
Step-by-step explanation:
it is equiangular.
sides are equal.
angles are equal.
all three sides are congruent.
Formula for the area of the triangle:
1/2 bh
b = base
h = height
#6.
Area = 36 in²
Base = 18 in
36 = 1/2(18)h
36 = 9h
36 ÷ 9 = h
4 = h
height = 4 in
#7.
Area = 2 ft²
Height = 1 ft
2 = 1/2 b (1)
2 = 1/2 b
2 ÷ 1/2 = b
4 = b
Base = 4 ft
#8.
Area = 42 in²
Base = 12 in
42 = 1/2 (12) h
42 = 6h
42 ÷ 6 = h
7 = h
Height = 7 in
Notice that the answers have no exponents (²). That is because they are used only on the area of shapes as units.
Since you find the area by multiplying things together, for example x · x = x², the exponent is there.
You do not need to worry about this being in the calculation. This will just be in units such as:
cm²
ft²
in²
m²
Just remember to use these exponents in the units for the areas.
THE 5 IDENTICAL SHELVES WOULD have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer
Answer:
28.26 ft^2
Step-by-step explanation:
Area of a circle is calculated using the following formula :
πr^2 (r: radius, and π is given as3.14)
the diameter is given as 6 and radius is equal to half of it so :
(3.14)*3^2 = 28.26 ft^2
How much turkey is in the pie?
The mass of the turkey in the pie is 1/4 of the weight of the chicken
200/4 = 50 grams
