Question

Find the total surface area of the figure below:

Answer 1

Answer:

95

Step-by-step explanation:

Formula -

Triangle Area - 1/2bh

Square - l x w

Triangle - 5 x 7 = 35/2 = 17.5

Since there are four triangle, we will multiply 17.5 x 4 which is equal to 70

Square  - 5 x 5 = 25

Now we add both 70 and 25 which is 95

So the total surface area is 95

Answer 2

Answer:

95

Step-by-step explanation:

Area of the triangles:

1. A = (base × height) ÷ 2
2. A = (5 × 7) ÷ 2
3. A = (35) ÷ 2
4. A = 17.5
5. Because there are 4 triangles, we can do our answer of one triangle × 4
6. So, 17.5 × 4 = 70

Area of a square:

1. The sides of squares are the same
2. A = L × W
3. A = 5 × 5
4. A = 25

Put them together:

1. Area of triangles + area of the square = surface area
2. 70 + 25 = suface area
3. 70 + 25 = 95

I hope this helps!
