Answer:
96 square units
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
- The length of the large rectangle is: 5
- The width of the large rectangle is: 7
=> Area of the large rectangle = length × width = 7*5 = 35 square units
- The length of the middle rectangle is: 7
- The width of the middle rectangle is: 4
=> Area of the middle rectangle = length × width = 7*4 = 28 square units
- The length of the small rectangle is: 7
- The width of the small rectangle is: 3
=> Area of the small rectangle = length × width = 7*3 = 21 square units
Area of top and the bottom triangles =2*
Total surface area = 35 + 28 + 21 + 12 = 96 square units
This has to do with place value.....the 3, since it is on the left of the decimal, is a whole number. The last number (6) is in the hundredths place..
so it is 3 56/100 which reduces to 3 14/25
Answer:
Step-by-step explanation:
The 22 degree angle is opposite to the 10 m side of the right triangle.
We need to find the length x of the hypotenuse.
<u>Use trigonometry:</u>
- sine = opposite/hypotenuse
- sin 22° = 10/x
- x = 10 / sin 22°
- x = 26.7 m (rounded)
1350 square feet. 45 *10 = 450 and you convert yards to feet using the ratio of 1:3; 1 yard per 3 feet
