So, first we have to separate the figure into three different shapes. What you get is a triangle, a semi-circle, and a rectangle. Lets first start with the triangle.
So, the formula to find the are of a triangle is A=1/2bh So the height of the triangle is 3 m and the base is 4 m. So, you have to do A= 1/2×3×4, which equals to 6 m² So, the area of the triangle is 6 m²
For the rectangle however, the formula to find the area is A=bh So the base of the rectangle is 6 and the height is 3 So, you do A=6×3, which is 18 So, the area of the rectangle is 18 m²
Now, for the semi-circle, the formula to find the area is A= 1/2×pi×r² So the radius of the semi-circle is 3 because 6÷2=3 So, what you do is A=1/2×3.14×3²,which equals 14.13
Finally, you have to add all the answers you just got, which would be 6+18+14.13, which would equal 38.13
Find the area of the Square. Then Use 3.14 to find the area of the Half Circle, and the Triangle's area too. Find the Formulas for each shape, plug in the numbers, and add the totals together.
