Surface area of 5 sides of square = 5a²= 5×8.2×8.2=336.2 Cm²

Surface area of pyramid= a²+2a √a²/4+h²= 8.2²+2×8.2√67.24/4+ 4.41= 142.79

Surface area of composite shape = 336.2+142.79-67.24= 411.75~ 411.8 Cm² !

Vitek1552 [10]

Answer: 2 1/3 feet

Step-by-step explanation:

Area of closet = 8 1/6 feet ²

Width of the closet = 3 1/2 feet

Length of the closet = Unknown

We should note that:

Area = Length × Width

Length = Area / Width

Length = 8 1/6 ÷ 3 1/2

= 49/6 ÷ 7/2

= 49/6 × 2/7

= 7/3

= 2 1/3 feet

The length is 2 1/3 feet

5x + 6y = 18 and 18x -15y =36
stira [4]
5x+6y=18

5x=18-6y

x=(18-6y)/5

Use that in the other equation
18(18-6y)/5 - 15y = 36

64.8-21.6y - 15y = 36

28.8=36.6y
.7868=y

Now put that number in for y on the first equation

5x+6(.78) = 18
5x + 4.68 = 18
5x = 13.32
x = 2.66
and y = .78
