1. First, do 12 x 8 to work out the area of the rectangle, which is 96ft.
Then, to work out the area of a circle, you use the equation πr² to help you. You would multiply π by the radius², which is 16. Now you have just worked out the area of a circle, but not a semicircle, so you would have to divide your answer by two to get the area of this, which would be 25.13 (rounded to 2 d.p).
To get the area of the whole shape, you just have to add the two totals together.
25.13 + 96 = 121.13ft.
Remember to put the units there, or you can lose marks.
Try your best with the next questions! I have written the formulas for the other shapes to help you work out the answers.
Area of a square = Multiply sides together.
Area of rectangle = Multiply width by length.
Area of a circle = Multiply π by the radius².
Area of a semicircle = Multiply π by the radius², and the divide by two.
Area of a triangle = Multiply the base by the height, and then divide by two.
Really hope this helps!

Answer as follows...
Step-by-step explanation:
interior angles are 3,4,5,6
exterior angles are 1,2,7,8
vertical angles are 2and3, 1and4, 6and7, 5and8
corresponding angles are 2and6 1and5 3and7 4and8
alternate interior angles are 4and5 3and6
alternate exterior angles are 1and8 2and7
same side interior angles are 3and5 4and6
A right triangle has a 30o angle. The leg adjacent to the 30o angle measures 25 inches.
What is the length of the other leg? Round to the nearest tenth.
