Answer:
884cm^2
Step-by-step explanation:
top triangle area=21*24/2=252
central triangle area=16*24/2=192
left n right triangle area (each)=22*20/2=220
total area of wood needed=252+192+220+220
=884cm^2
Answer:
Step-by-step explanation:
Total wood needed is the sum of the four triangles shown in the diagram.
The area can be calculated by using the triangle's area formula: 1/2xbasexheight
Total area=(1/2x24x21)+(1/2x24x16)+2x(1/2x20x22)
=884cm^2

Answer:
The number 1 is not necessary when expressing powers of one. For example, you needn't write "5" as 
.
Step-by-step explanation:
Answer: 5 and 4
Step-by-step explanation:
Perimeter = 2 ( L + W)
18 = 2(L + W) divide through by 2
9 = L + W
9 - L = W
Area = L * W
20 = L (9 - L)
20 = 9L - L^2
L^2 - 9L + 20 = 0 factor
(L - 5) (L - 4) = 0
Set both factors to 0 and solve for L
L = 5 and L = 4
Answer:
x=17
Step-by-step explanation
i just did the exact same question on a test and got it right .
Find how many square feet it is
assumng the table is a rectangle
area=legnth times width
area=10 times 17=170
16 per 1 square foot
16 imes 170=2720
answer is $2720
1 1/3 repeating because you will get the dash over it
