Sagot :

Answer:

80

Step-by-step explanation:

3x8=24

7x8=56

24+56=80

For the 7x8, I'm not including x1/2 also because if we do it once without the x1/2, then it will take it for 2 triangles, and that's what we have here.

So hence, the area of the trapezoid is 80sq.units

Thanks!

Solution:

Note that:

  • Area of trapezoid = (a₁ + a₂)h/2

Use the formula to find the area of the trapezoid.

  • (a₁ + a₂)h/2
  • => (3 + 7 + 7 + 3) x 8/2
  • => (20) x 8/2
  • => 160/2
  • => 80 units²
