Answer:
9800 cm^2
Step-by-step explanation:
The area of a square is just the length of one of the sides squared. In the first image it's given that one of the sides is 70 cm and the shape is also a square pyramid so the base is going to be a square. So the area the base is (70 cm) ^ 2 = 4,900 cm^2. The area of a triangle is 1/2 bh. The base is given in the first image which is 70 cm and the height is also given which is 140 cm. This gives you the equation 0.5 * 140 cm * 70 cm = 4900 cm^2. Adding these two values gives you 9800 cm^2
Answer:
Step 2 has the error because they added the five to -3 and got -8 when they should have gotten 2.

Answer:
41 kg
Step-by-step explanation:
A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
8^2 + 5^2 = c^2
64 + 25 = c^2
89 = c^2...take the sqrt of both sides...this eliminates the ^2
sqrt 89 = c
9.4 = c....shortest path is 9.4 km
