Question

Please Help I Don't Understand.

Answer 1

Explanation:

Area Formula= 1/2(base 1 + base 2) x height

You are missing base 1, which would be equal to 17. This is because base 2, which is 23, subtracted by 6 or (3+3), is 17.

So- Base1 = 17, Base2 =23, Height = 17

Formula with variables added= 1/2(17 + 23) x 17

When this equation is solved, the answer is - 340

Answer 2

• MN=23-3-3=17

Now

Area of trapezium

• 1/2(sum of parallel sides)(Height)
• 1/2(17+23)(17)
• 1/2(40)(17)
• 20(17)
• 340units²
