Find the area of the shape shown below.
7
3
3

Split it into two shapes a square and a triangle.
Square = 3 x 3 = 9
Triangle = 1/2 x base x height
The height would be the side of the square = 3
The base would be the length of the top line minus the length of the side of the square = 7-3 = 4
1/2 x 4 x 3 = 6
Total area = 6 + 9 = 15 square units.
Answer:
Step-by-step explanation:
area of a trapezoid = (a + b) * h/2
where a = 3, b = 7, h = 3
plugin values into the formula:
A = (3 + 7) * (3/2)
A = 15 sq. units.
