Answer:
26.5 units²
Step-by-step explanation:
I am splitting the figure into a rectangle and two triangles to make this easier for me.
The rectangle is b•h so 5•4 = 20 units²
Area of triangle=1/2bh
The left triangle is (3•3) ---> (9) ---> 4.5 units²
The right triangle is (2•2) --->(4) ---> 2 units²
Then add it all up: 20+4.5+2 = <u>26.5</u><u> </u><u>units²</u>

Answer: See explanation
Step-by-step explanation:
Total number of text messages = 800
Amount used by Tommy and Mary = 1/2 × 800 = 400
Number of messages uses by Jack and Stefanie = 240
The expression to find the number of messages Cathy uses will be:
= 800 - (1/2 × 800) - 240
Since the expression is 800 - (1/2 × 800) - 240, the number of messages that Cathy will use will be:
= 800 - (1/2 × 800) - 240
= 800 - 400 - 240
= 160 messages
