Question

What is the area in square units?

Answer 1

45 square units

Explanation:

Split the figure up into pieces. You can see that you can divide it into a rectangle and a triangle. Count the dimensions of the rectangle, and note the value. It's 7 by 5, or 35 square units. Keep that in mind. Moving to the triangle, count what the dimensions would be if it were another rectangle. In this case, that would be 4 by 5. Instead of taking the full value of 20, we should divide it by 2, since it's a triangle. In this case, add 10 to the value of the first rectangle. This gives us an answer of 45 square units.

Answer 2

I am not sure, I think it's 45

Step-by-step explanation:

The figure is a trapezium and area of a trapezium is 1/2 h ( sum of parallel sides)

Area = 1/2 x 5(there are 5 squares) {7 +10 + sum of the 2 halves => 1}

= 1/2 x5(7+10+1)

= 1/2 x 5 x 18

= 45
