Complete Question:

Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.

Part A= 12 x ? = ? ft²

Part B= 0.5 x ? x 9 = ?ft²

Part C= 0.5 x 7 x ? = ?ft²

Total Area= ?ft²

Answer:

A = 108ft^2

B = 27ft^2

C = 24.5ft^2

Area = 159.50ft^2

Step-by-step explanation:

Given

See attachment

From the attachment;

Part A is a rectangle with dimension 9ft by 12ft

So,

A = 12ft * 9ft

A = 108ft^2

Part B is a triangle with dimension: height = 6 and base = 9

The height is calculated as:

Height = 12ft - 6ft = 6ft

And the base is:

Base = 18ft - 9ft = 9ft

So, the area is:

B = 0.5 * 6ft * 9ft

B = 27ft^2

Part C is a triangle with dimension: height = 7 and base = 7

So, the area is:

C = 0.5 * 7 * 7ft^2

C = 24.5ft^2

Total Area is:

Area = A + B + C

Area = 108ft^2 + 27ft^2 + 24.5ft^2

Area = 159.50ft^2

X + Y = 3,500 X - Y = 2,342
LUCKY_DIMON [66]
X + y = 3500 -------------- (1)
x - y = 2342 --------------- (2)

(1) + (2):
2x = 5842
x = 2921 -------------- Sub into (1)
x+ y = 3500
2921 + y = 3500
y = 3500 - 2921
y = 579

----------------------------------------------
Answer: x = 2921, y = 579
----------------------------------------------

Calculate the length
Usimov [2.4K]

Answer:

19.3 cm

Step-by-step explanation:

A F² = AB² + BF²

BF² = BC² + CF²

= 11² + 5² = 146

A F² = AB² + BF²

A F² = 15² + 146 = 371

A F = sqrt(371)

A F = 19.26136028
