This formula is used to find the median in a group data which is located in the median class. Median, m = L + [ (N/2 – F) / f ]C
L means lower boundary of the median class N means sum of frequencies F means cumulative frequency before the median class.
Hope this helps :))
Answer:
Step-by-step explanation:
1) length = x m
breadth = x/2 m
Area of rectangular floor = 32 square m
Length = 8 m
Breadth =8/2 = 4 m
Perimeter = 2*(length + breadth) = 2*(8 + 4)
= 2*12
= 24 m
2) Perimeter of square = 12 cm
Side of a square = perimeter ÷ 4 = 12 ÷ 4 = 3 cm
Area =side *side = 3*3 = 9 cm²
3) Perimeter of square field = 60 m
Side = Perimeter ÷ 4 = 60 ÷4 = 15 m
Area of square = 15 * 15 = 225 m²
4) Perimeter of rectangle = 28 cm
breadth = (Perimeter ÷ 2) - length
= (28 ÷2) - 8
= 14 - 8
Breadth = 6 cm
Area of rectangle = 8 * 6 = 48 cm
Answer:
26 + 18 = 44 and 18 + 34 = 52.

Step-by-step explanation:
Answer:
15ft by 18ft
Step-by-step explanation:
Start with 2.5 divided by .25
That equals 10
10 times 1.5 ,because we know it takes ten .25inches to equal 2.5 and 2.5, is the size of one of the sides.
10 time 1.5 is 15ft
3 divided by .25 is 12
using the same logic and math as stated above we know 3 x .25 equals 12 by 12 quarter inches to make 3 inches
12 x 1.5 Same logic as before
12 x 1.5 equals 18ft
The kitchen is 15ft by 18ft
