Answer:
Step-by-step explanation:
Find the area of the base
The base is a square.
The formula is Area = s^2
s = 1.5
Area = 1.5^2
Area = 2.25 sq cm.
Area of 1 triangle
h = 2.4
b = 1.5
Area = 1/2 * b * h
Area = 1/2 * 1.5 * 2.4
Area = 1.8 cm^2
Area of 4 triangles
Area = 4 * area of 1 triangle
Area = 4 * 1.8
Area = 7.2
Total Area = 2.25 + 7.2 = 9.45 cm^2

Answer:
m∠A = 45.86°
Step-by-step explanation:
A rough sketch of the triangle is shown in the attached pic.
When 3 sides are given and we want to solve for an angle, we use the Cosine Rule. Which is:

Where a, b, p are the lengths of 3 sides (with p being the side opposite of the angle we are solving for) and P is the angel we want to solve for
Thus, we have:

The answer is 1.5
1.2=1.0
1.3=1.1
1.4=1.2
1.5=1.2
