Answer:
just add the area of the triangle(formula 1/2bh) and the area of the square(formula bh)
so 1/2(6*height)+8*7
Step-by-step explanation:
Given that median area is 15 square units.
Hence rectangle C in the middle has 15 square units.
Its dimensions can be width= 5 and length = 3
SInce B is smaller than C and has the same length, B has lengh of 3 with area = 9 sq units.
D has the same perimeter = 16 units. Since D is a square, side of D = 4 units.
Now D and E have the same length. Hence length of E = 4 units.
Width of E = width of C = 5 units.Thus makes the area of E as 20 sq units.
Rectangle A has length =3 and width can be less than 3 since area is smaller than B.
so A has length= 3 width = 2 with area = 6 sq units.
Answer:

Step-by-step explanation:










<u><em>Remark</em></u>:
You can simplify moreover if you want to.
Since the volume of an object = \frac{4}{3}\times \Pi r^{3}
Volume= \frac{4}{3}\times (3.14) (243)^{3}
Volume= 60074091 mm^{3}
