Answer:
You have to find the hypotenuses of the triangle to get the area of the entire area of the shape. Once you have the length of the hypotenuses then you can use that value to calculate the area of the triangle and the area of the box above.
Hyp = sqRoot ( 3.16^2 + 6.32^2) = sqroot(50) = 7.07
Area of Triangle = 1/2 x b x h = 1/2 x 6.32 x 3.16 = 9.99= 10
Are of square above triangle = l x w = 7.07 x 7.07 = 49.99 = 50
Total area = 10 + 40 +10 +50 = 110 SQ UNITS

It's A .
Step-by-step explanation:
The order in which they are chosen is immaterial so it is a combination.
Number of combinations of 2 from 6 = 6C2
= 6*5 / 2*1 = 15.

Answer:
The time it takes to boil 2.2 litres of water is approximately 141 seconds
Step-by-step explanation:
The given parameters are;
The relationship of the variables, T and A is a proportional, therefore, we have;
T ∝ A, or T/A = k = Constant of proportionality
The time it takes to boil 2.8 liters of water = 180 seconds
∴ When A = 2.8 litres, T = 180 seconds, from which we have;
k = T/A = 180 s/(2.8 L) = 450/7 s/L
k = 450/7 s/L
When A = 2.2 litres, we have;
T/A = k
∴ T = k × A
Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;
T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141. s
The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141. seconds ≈ 141 seconds given to the nearest second.
