Find the area of the shape
MAVERICK [17]

Answer:

A=42.5

Step-by-step explanation:

First you split this shape into a square and a triangle.

The area of the square is 5✖️5=25.

Then, there is a triangle left.

We do not know about the hypotenuse, but the sides are 5 and 7.

5✖️7=35/2<-- because it is a triangle. =17.5

You add both areas, and you get the total of 42.5.

Hope this helps!
