Answer:

Step-by-step explanation:

A=(b1+b2/2)h

The formula is area= base 1 plus base 2 over 2 times the height.

The two bases are 17 cm. Let's add that in our formula.

A=(17+17/2)h

17+17= 34. Since 34 is over 2 in the parentheses, let's simplify that first.

A=(34/2)h

A=(17)h, because 34 divided by 2 is 17

The height, h, is 9 cm. Let's subsitute that into h.

A=(17)9

17 times 9 equals 153, so the area is 153² cm. :)
