Area of the large rectangle : 4x15 = 60

Area of the small rectangle : 4x6 = 24

Area of the small right triangle : (4x6)/2 = 12

Area of the large right triangle : High = 8 &  side =15-6=9
So its area is( 8x9)/2 =36

Total area =60+24+12+36 = 132 units²

A rectangular park had a perimeter of 18 miles. It is 7 miles wide. What is the area of the park?
4vir4ik [10]
Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18

a = ?
b = 7

18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2

Area = a * b
Area = 2 * 7 = 14 miles2

Please help me please will give brainliest to anyone who is good <br><br>show your reasons ​
lana [24]

Answer:

Option D

Step-by-step explanation:

She is selling tickets for $10 each, and if 1,007 people attended, that would be: $10,070 in proceeds. So, you then subtract that from the balance at the bank: -$3,200.

-$3,200 + $10,070 = $6,870 balance.

PLEASE HELP ME I BEG I REALLY NEED HELP WITH THIS PROBLEM!
lozanna [386]
Area = length x width

x² + 12x = l * x


A.  

First, you factor x from x² + 12x

x^{2} +12x=x(x+12)

area = x (x+12)

area = (x+12) * x

Length = x + 12



B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220
        

Hope this helps :)
