Answer: 72
Explanation:
A = 1/2(d1)(d2)
A = 1/2(12)(12)
A = 144/2
A = 72
Basically you can write taking from something or using something 20 times. Here are three examples.
- You borrowed 1 dollar from someone 20 times.
- You descend 1 meter at a time (like a submarine).
- There are 20 candies in the jar. Each day you eat 1 candy.
Add up all the hours so 5+2+1=8
Math would be 2:8 and I think u can simply it to 1:4
Hope it helps
L = 2W
A = 50
A = L x W
50 = 2W x W
50 = 2W^2
W^2 = 25
W = 5
so L = 2W = 2(5) = 10
P = 2(L+W)
P = 2(10+5)
P = 2(15)
P = 30
answer
P = 30 in
