Answer:
60cm^2
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) (5cm) = 60 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
1 day = d
0 + 3d = 4 + 2d
3d = 4 + 2d
d = 4
It'll take 4 days
Hope this helps ^-^

trust me it's right it might be easier if you use paoer
It will be 300 in the account after he contributes
Corresponding sides on either side of ED are proprotional, so
(x+2)/112 = 62/99.2
x +2 = 112*62/99.2 = 70
x = 68 feet
