Whats the area and perimeter to the shape below?

Anarel [89]

Answer:

Step-by-step explanation:

a) Area of white square = side *side = 8 * 8 = 64 sq.mm

Area of 4 white square = 4 * 64 = 256 sq.mm

compound shape

length = 3 cm = 30 mm

Width = 2 cm = 20 mm

Area of compound shape = length *width = 30 * 20 = 600 sq.mm

Area of the shaded part of the compound shape =

Area of compound shape - Area of 4 white square

= 600 - 256

= 344 sq.mm

b) Perimeter of compound shape = 2*(length + width)

= 2*(30 +20)

= 2* 50

= 100 mm

An outdoor amphitheater has 100 seats in the front row and each subsequent row has 6 more seats than the previous row. how many

fiasKO [112]

If each row have 6 more seats than the previous, then there is a common difference of 6 seats. This, in turn, becomes an arithmetic progression, with a₁ being 100 and d being 6. Now, we want to know the total number of seats when n = 23, so we need to use the sum of an arithmetic progression form:

$S_n = \frac{n}{2}(2a_1 + (n - 1)d)$
$S_{23} = \frac{23}{2}(2(100) + 22 \cdot 6)$
$S_{23} = \frac{23}{2}(200 + 132)$
$S_{23} = 3818$

Hence, there are 3818 seats in the first 23 rows.
