Step-by-step explanation:
Area of big square: A=8*8=64 sq m
Area of small squares: A=4t*t
Area of shaded region: A=64-(4t*t)
so 90 x 9 = 980 minutes so that is the answer
Answer:
Oh cool! The answer is 90 since a and c or parallel, b cuts through them perpendicularly, forming a right angle.
6X8=48 10 more is 58
