A) Perimeter of Trapezium = 8+5+6+15.5
= 34.5in
Area= 1/2*(a+b)*h
=1/2*(8+15.5)*4
=47in^2
B)Perimeter= 12+6+8.5
=26.5mm
Area=1/2*b*h
=1/2*12*4
=24mm^2
Fourths, then b. Sorry if late.
I’m pretty sure A is true <3
Answer:
5 rolls
Step-by-step explanation:
The perimeter lengths are the same because it's a square. So 12 times 4 is 48. You would need a minimum of 5 rolls because each roll as a length of paper of 10 feet. So 40 feet plus 8 would round to 50. That's why it would be 5 rolls.
Honestly? Just review your notes and try to work out the problems yourself before taking a look at the answer. You can also google specific topics that the test will cover and try the practice problems.
