Answers

and what else is there do you want the length? and the width?.
okay so a rectangle right? one side is 6.5, since one side should be perpendicular to another, that's 13 units off. So 34-13=?21, so 21/2 is 10.5.

What the area of this figure

Answers

Let's first start by finding the area of the bigger rectangle.

Area = Length × Width

Area = (4) (3)

Area = 12 ft².

Now, let's find the area of the smaller rectangle.

Area = Length × Width

Area = (4) (1)

Area = 4 ft².

Finally, we need to add the areas of both of the figures to fo find the area of the whole figure.

12 ft² + 4 ft² = 18 ft².
