Answer:

6801.5 ft²

Step-by-step explanation:

Draw a dashed line to extend the 48 ft side.

To the right of this dashed line you have a rectangle of 55.5 ft by 98 ft, whose area is (55.5 ft)(98 ft) = 5439 ft².

To the left of this dashed line you have a triangle.

Its base length is (98 ft - 48 ft), or 50 ft.

Its height is (110 ft - 55.5 ft) = 54.5 ft.

Since the area of a triangle is given by A = (1/2)(base)(height), the area of this particular triangle is A = (1/2)(50 ft)(54.5 ft) = 2725/2 = 1362.5 ft².

The total area of this figure is then (1362.5 ft² + 5439 ft²), or 6801.5 ft².

Step-by-step explanation:

The interior angle of the 8-sided polygon is

\frac{180(8-2)}{8}=135^{\circ}

The interior angle of the 10-sided polygon is

\frac{180(10-2)}{10}=144^{\circ}

Taking the difference, we get b=9^{\circ}

krok68 [10]

Answer:

the amount after 5 years using compound continuously is $135.03

Step-by-step explanation:

The computation of the amount after 5 years using compound continuously is as follows

= Principal × e^(rate × time period)

= $110 × e^(4.2% × 5)

= $110 × 1.227525065

= $135.03

Hence, the amount after 5 years using compound continuously is $135.03

We simply applied the above formula so that the correct value could come

And, the same is to be considered
