Cut the figure into 2 pieces: the big rectangle at the top and the narrow rectangle at the bottom.
Area is length x width.
Start with the big rectangle. Take 8cm (your length) and multiply it by 6cm (your width). You get 48 cm.
Now for the narrow rectangle. Take 12 cm (your length) and multiply it by 2cm (width) to get 24 cm.
Add the two measurements up, 48cm + 24 cm and your answer is 72 cm.
Answer:
Sarah = 78
Lee = 79
Step-by-step explanation:
98 + 100 + 65 + 78 + 98 + 46 + 100 + 100 + 45 + 50 = 780
780÷10= 78
97 + 67 + 89 + 99 + 100 + 45 + 79 + 89 + 58 + 67 =
790
790÷10=79
Take 28% of 500 which is 140 then add that to 500.
The answer is 640.
Fifteen thirds equals five
And
consecutive angles have sum 180°
- 7y+3+86=180
- 7y+89=180
- 7y=91
- y=13
So
- 5z+4+86=180
- 5z=180-90
- 5z=90
- z=14
