Explanation:

to understand this

you need to know about

  • area of triangles
  • area of rectangle
  • PEMDAS

tips and formulas:

  • rectangle opposite sides are equal
  • area of rectangle:l×w
  • area of triangle:½×h×b

let's solve:

the area of the rectangle is

4×7 in²

28 in²

the area of above triangle is

½×6×7 in²

3×7 in²

21 in²

the area of left side triangle is

½×5×4 in²

2×5 in²

10 in²

therefore,

the area of the polygon is

28+21+10 in²

59 in²
