Step-by-step explanation:
we have

we know that

substitute

Remember that
When multiplying decimals by 10, move the decimal point one space to the right
In this case move the decimal point eight spaces to the right

therefore
The number written in standard form is 
A= 1/2(bh)
h=4b
50= (1/2)(b*4b)=2b^2
25=b^2
base = 5 that's your answer
height = 4xb = 4x5=20
Answer:
Our two numbers are 50 and 20
Step-by-step explanation:
Sum means add together
Difference means subtract each other
x + y = 70
x - y = 30
subtract from each other
2x = 100
divide both sides by 2
x = 50
our first number is 50
50 + y = 70
subtract both sides by 50
y = 20
Our two numbers are 50 and 20
