You have to find the area of the little square first, so that's 6 x 5 which is 30. Then find the area of the shaded part. 15 x 15 = 225. Then subtract both numbers. And you'll get "195 m" which is your answer.
Answer:
195 m
Explanation:
first find the area of the whole square (15x15=225) then find the area of the rectangle inside (6x5=30) then subtract 30 from 225 which leaves you with 195
