Answer:
24 cm²
Step-by-step explanation:
We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...
K = sr
where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.
K = (12 cm)(2 cm) = 24 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
Answer:
5050
Step-by-step explanation:
∑_{n=1 to 50} (4n-1)
a1=4×1-1=3
a2=4×2-1=7
a3=4×3-1=11
......................
......................
......................
a50=4×50-1=199
n=50
Sn=n/2(a1+an)
S50=50/2(3+199)=50/2×202=50×101=5050
Step-by-step explanation:
4(m+7)=48
m+7=48/4
m+7=12
m=12-7
