Answer:
67.5 units²
Step-by-step explanation:
We can break this problem down in two parts: The upper triangle and the lower trapezoid.
The upper triangle:
Use the formula to compute the area of the triangle. Base = 10 and Height = 7.
1/2 (10)(7)
1/2 (70)
=35 units².
The lower trapezoid:
Use the formula to compute the area of the trapezoid. Base 1 = 10, Base 2 = 3 and Height = 5.
1/2 (10 + 3)(5)
1/2 (13)(5)
1/2 (65)
=32.5 units²
So, add the two areas of each shape:
35 + 32.5 = 67.5 units².
Answer:
75 square inches
Step-by-step explanation:
Area of a Triangle = 1/2 × Base × Height
From the above question:
Base = 30 Inches
Height = 5 inches
Hence:
Area = 1/2 × 30 in × 5 in
Area = 75 square inches
Therefore, the area of one of the triangular pieces of wood that she needs to build the ramp is 75 square inches
