Answer:
730mm²
Step-by-step explanation:
Answer:
S.A = 730mm²
Step-by-step explanation:
Since the solid is made up of two rectangles. Then the surface area (S.A) would be
S.A = area of first rectangle + area of second rectangle
Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is
25mm x 21mm = 525mm²
Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is
41mm x 5mm = 205mm²
Therefore
S.A = 525mm² + 205mm² = 730mm²

Answer:
86
Step-by-step explanation:
(2+2=4) 4 to the 3rd power is 64. 150 minus 64 is 86
No it doesn't. 2*0.5 + 5*0 = 1, not 19
