Answer:
I think it is 671
Explanation:
The 2 sides are the same length because of those dashes on them so 61 + 61 = 122.
144 - 122 = 22 which is the base
Area is "Base times height divided by two"
The height is 61
so the area is (22 x 61) / 2
22 x 61 = 1,342
1,342 divided by 2 is 671
I think this is right, im sorry if it is wrong.
